Abstract:

N-containing carbon-based materials have been employed with claimed improved performance as an adsorbent of acidic molecules, volatile organic compounds (VOC), and metallic ions; catalyst; electrocatalyst; and supercapacitor. In this context, the present work provides valuable insights into the preparation of N-doped activated carbons (ACs) by thermal treatment in NH3 atmosphere (ammonization). A commercial AC was submitted to two kinds of pretreatment: (i) reflux with dilute HNO3; (ii) thermal treatment up to 800 °C in inert atmosphere. The original and modified ACs were subjected to ammoniza

Abstract:

Introduction. The problem of providing the population with drinking water with guaranteed quality, safety, and physiological usefulness is highly relevant for many regions of Russia. The use of chlorination for disinfection of the water is a potential cause of the formation of excess concentrations of organochlorine compounds in it, including trihalogenomethanes, which leads to elevated levels of carcinogenic risk. The study’s object was: data on the content in water of centralized water supply systems of carcinogenic organochlorine compounds - chloroform, dichlorobromomethane and chlorodibrom

The results of the studies made it possible to establish that differences in the content of sulfate and phosphate ions in the NH4+–PO43—SO42-–H2O system lead to a significant change in the solubility and position of the crystallization fields and, as a result, to a change in viscosity.

Abstract:

The article presents the research results on obtaining the highly effective complex fertilizer sulfoammophos based on wet-pprocess phosphoric acid of various concentrations. This product is not produced in Kazakhstan; to launch it at the Mineral Fertilizers Plant, it is necessary to study the effect of acid concentration and soluble impurity content on obtained fertilizer composition. Standard chemical and instrumental methods of analysis were used to identify the obtained salts. It was found that when evaporating wet-pprocess phosphoric acid in precipitator presence the fluorine content decre

Abstract:

The aim of this paper is to study the use of a mixture of commercial clay namely K10 and a natural Romanian sodium bentonite in the adsorption of NH3 contained in air using fixed and fluidized bed gas-solid reactors. Qualitative (DRX) and quantitative (XPS, DTG) analysis were performed. Clays were agglomerated and treated with NH3. Adsorption isotherms were determined under several operating conditions. Results showed that after 70 minutes of ammonization, activated agglomerated clay exhibits a superior capacity of adsorption (2.09 mmoles NH3/g clay instead of 1.057 mmoles/g clay for natural c

Abstract:

Abstract Coal and biomass are regularly used in the preparation of activated coke. In this paper, coal and biomass (poplar bark) were co-pyrolyzed, and activated coke was prepared by physical “one-step activation,” followed by ammonization and additional activation by potassium carbonate (K2CO3). The activation temperature was set at 800 °C, the time was 60 min, and the activation atmosphere contained 10% steam and 20% CO2 by volume in nitrogen. The physical and chemical properties of activated coke prepared by “one-step activation method” and “two-step activation method” were compared. The mo

Abstract:

Humic acids (HA) constitute the major fraction of natural organic matter in water supplies. HA are very problematic with regard to drinking water treatment and supply since, not being completely removed by conventional treatment processes, they react with chlorine resulting in formation of carcinogenic and regulated disinfection-by products. Adsorption of brown (BHA) and gray (GHA) fractions of humic acid on starting and modified mesoporous activated carbons was investigated. BHA and GHA are fractions of humic acid extracted from young brown coal (Czech Republic) which differ essentially in th
