The transportation is one of the largest contributor to air pollution in Indonesia, especially in large cities. Fuel gases from combustion in motor vehicles, such as oxides of nitrogen (NOx) will be emitted to the ambient air. Increasing the concentration of NOx in ambient air can be bad for human health, especially with regard to upper respiratory tract disease. Therefore, the development of methods which are environmentally friendly for controlling air pollution remains to be done.

To better understand the kinetic mechanisms of nitrate photolysis, the effects that ionic strength in solution have on nitrate ion symmetry breaking are needed. Different solvation environments induce nitrate bonding motifs that may be correlated to the product ratio. Fourier-transform infrared spectra of aqueous nitrate–ion solutions were obt

Nitrate contamination is a drinking water concern in many areas in the world, especially rural communities. Excess nitrate can cause several environmental and health problems. The maximum acceptable concentration of nitrate in drinking water is set to be 45 mg /L as nitrate by USEPA. One of the most common methods for nitrate removal from water is ion exchange using nitrate selective resins. Although these resins have a great capacity for nitrate removal, they are considered non regenerable. The ability to regenerate these resins multiple times will increase the environmental and economic sust

Abstract Corrosion behaviour of high purity aluminum was evaluated by potentiodynamic polarization measurements in 50 % hydrogen peroxide as a function of chloride and nitrate concentrations and in the presence of some amino(alkyl)phosphonates which are widely used as stabilizers against catalytic decomposition for hydrogen peroxide. Chloride ions, already at very low concentrations, induce pitting type corrosion for aluminum. This pitting can be prevented by sufficient additions of nitrate ions. Ammonium nitrate and nitric acid were equally efficient.

Abstract Slow strain rate tests were performed to evaluate the effect of simulated groundwater chemistry variations on the stress corrosion cracking (SCC) susceptibility of mill-annealed Alloy 22. Tests were conducted in which the constituent anionic species were removed selectively from simulated concentrated water (SCW). SCC was observed in SCW and its variations [removal of nitrate, sulfate, fluoride or chloride] at a high anodic potential of 0.4 VSCE at 95°C (203°F). Although the bicarbonate ion is the predominant constituent in SCW causing SCC, a synergistic effect exists between the bica

Abstract The stress corrosion cracking (SCC) susceptibility of α-brass in 0.01 M copper sulfate with additions of 0.1 M of mono-and di-ethanolamine was studied as a function of the applied potential. In monoethanolamine solutions a potential dependent SCC process was found. In diethanolamine, on the other hand, SCC was observed only at the passivity breakdown potential, and it was attributed to the action of the sulfate ions. Transgranular SCC was found for Ag-Cd alloys in the presence of silver nitrate solutions, the higher the silver ion concentration in the solution the higher the crack vel

ABSTRACT Ozone has been used commercially for the treatment of drinking water for nearly a century -- yet definitive studies identifying byproducts of organic and inorganic solutes have been conducted only within the past 15 years. In this paper, the author will present results of an extended literature survey on the subject, and extrapolate this information to what byproducts can be expected to form during ozonation of recycling cooling waters. In general, organic byproducts of ozone oxidation consist of aldehydes, acids, aldehyde-acids, keto-acids, polybasic-acids, and peroxides. Some of the

Abstract Alloy 22 is susceptibility to crevice corrosion in concentrated chloride solutions at elevated temperature. A number of oxyanions, most notably nitrate, sulfate, and carbonate, inhibit the aggressiveness of the chloride ion. The ratio of aggressive to inhibitive anions is a key parameter in predicting the possibility of the crevice corrosion of waste packages in the Yucca Mountain repository. The results of a preliminary experimental program to study the effects of chloride and nitrate ions on the propagation and stifling of the crevice corrosion of Alloy 22 are described. A coupled-e

Abstract Low carbon steel (LCS) exposed to concentrated solutions of urea-ammonium nitrate (UAN) can develop either a fully or a partially passive film. The integrity of the film phase that develops depends primarily on pH and, to a lesser extent, on nitrate ion concentration. Urea interacts synergistically with nitrate in the presence of low-carbon steel; surface adsorption may be the mechanism leading to higher true current densities. Based on this information, an inhibitor was developed that protects the naturally formed passive film from pH depressions.

Ammonia waste removal in recirculating aquaculture systems is typically accomplished via the action of nitrifying bacteria in specially designed biofilters that oxidize ammonia to produce nitrate. In the majority of these systems nitrate is discharged to the environment through frequent water exchanges. As environmental considerations have made it necessary to eliminate nitrate release, new strategies for nitrate consumption are being developed. In the funding period we showed that ammonia removal from wastewater could take place by an anaerobic ammonia oxidation process carried out by bacteri

Although nitrate fertilizers are critical for enhancing crop production, excess application of nitrate fertilizer can result in ground water contamination leading to the so called "nitrate problem". Health and environmental problems related to this "nitrate problem" have led to serious concerns in many parts of the world including the United States and Israel. These concerns have resulted in legislation limiting the amount of nitrate N in drinking water to 10mg/g. Development of a fast, reliable, nitrate sensor for in-situ application can be extremely useful in dynamic monitoring of environmen

This research focuses on developing two analytical methods for forensic investigations using electrochemical detection and surface-enhanced Raman spectroscopy. For electrochemical analysis, screen-printed carbon electrodes are used to detect metals and nitrate/nitrite compounds commonly found in gunshot residue. Gold electrodeposition and copper modification enhance sensitivity and catalytic activity, respectively. Additionally, a screen-printed gold electrode modified with gold nanoparticles enables surface-enhanced Raman spectroscopy, requiring only a single drop of sample solution. Testing

In this 1-year feasibility study, we tried polymerization of several different monomers, commercial as well as novel, specially designed and synthesized for this project in the presence of the nitrate ion to produce imprinted conductive polymers. Polymers 1 and 2 (shown below) produced a response to nitrate, but one inferior to that produced by a polypyrrole (Ppy)-based sensor (which we demonstrated prior to this study). Thus, we elected to proceed with improving the stability of the Ppy-based sensor. In order to improve stability of the Ppy-based sensor, we created a two-layer design which in

The contamination of surface and subterranean drinking water supplies with nitrogen-laden agricultural wastewater is a problem of increasing concern in the U.S. and Israel. Through this research, we found that bacteria could utilize common organic wastes (e.g. paper, straw, cotton) as carbon sources under anaerobic conditions, and reduce nitrate concentrations in wastewater to safe levels. Two species of bacteria, Cellulomonas uda and a Comamonas sp., were required for dentitrification. Celulomonas uda degraded cellulose and reduced nitrate to nitrite. In addition, it excreted soluble organic
