This work focused on purifying copper electrolytes from a bismuth impurity on a laboratory scale. The electrolyte came from Polish copper electrorefineries with the content of main components, g/dm3: 49.6 Cu, 160 H2SO4. The electrolyte was enriched in bismuth by Bi2O3 addition. Purification of bismuth contamination was carried out using selected agents with adsorbing effects, such as barium hydroxide octahydrate, strontium carbonate, barium carbonate, barium and lead sulfates. The trials were performed until achieving the Bi level—below 0.1 g/dm3. During the experiments, it was noticed that el

A method for calculating the scattering capacity using a sectional anode for the electrolytic-plasma polishing variant, both with and without taking into account the edge effects, has been developed and tested. An increase in the scattering capacity of the electrolyte is shown to depend on both an increase in the hydrodynamic parameters of the sulfate electrolyte and a decrease in the processing voltage, in the electrolyte temperature, and in the concentration of ammonium sulfate in the electrolyte. The maximum scattering capacity (taking into account the edge effects) was found to be 95% at a

Influence of nickel sulfate additives in silicate-alkaline electrolyte for microarc oxidation of titanium alloys on properties of formed electrolyte-plasma coatings was investigated. The influence of the component composition of the electrolyte on the chemical composition of the coatings, their protective ability, porosity and electrical characteristics was established. It is shown that the most corrosion-resistant coatings are formed from electrolytes with a low content of nickel sulfate, and an increase in the content of nickel in the coating does not lead to a significant change in its elec

Abstract Glycerolysis is the simplest, least expensive, and most prevalent technique for producing mono-diacylglycerol (MDAG). MDAG, a product derived from palm oil, is crucial to the fat-based food sector. Chemical glycerolysis generally leaves crude MDAG with glycerol residues that exceed the European Union’s maximum (up to 7.5%); thus, it must be purified. Cream demulsification is one of the conventional ways of purification for separating glycerol residues from MDAG.

Introduction. The use of restored parts of motor vehicles makes it possible to reduce the financial costs of repairing equipment. The cost of the restored parts should not exceed 50% of the cost of the new part. Increasing the productivity (deposition rate) of an electrolytic copper coating during the restoration of parts of motor vehicles requires taking into account the technological and economic aspects of the restoration process.

Abstract For well casings it is difficult to directly measure cathodic protection potentials along the length of the well casing. The E-log I criterion is described in RP0186-2001(1) “Application of Cathodic Protection for External Surfaces of Steel Well Casings”, which stated that adequate protection is achieved with “a voltage at least as negative (cathodic) as that originally established at the beginning of the Tafel segment of the E-log I curve. This voltage shall be measured between the structure surface and a saturated copper-copper sulfate half cell contacting the electrolyte.” In order

Abstract Molten carbonate fuel cell (MCFC) power plants operating on fuels derived from the gasification of coal are likely to be exposed to ppm levels of various sulfur contaminants in the fuel. In a recently completed program conducted at the Institute of Gas Technology (IGT) addressing the performance loss associated with sulfur contaminants in the fuel, a number of corrosion related problems were uncovered on the oxidant side of the cell. These problems included the accelerated corrosion of cathode side hardware, the conversion of carbonate electrolyte to sulfate on the surface of the cath

Missouri S and T investigated alternative new methods to the existing practice of measuring the structure-to-electrolyte potential to assess the level of cathodic protection (CP) of a buried pipeline. The measurement of a negative 850 mV DC pipeline to soil potential relative to a copper/copper sulfate reference electrode has been used for decades as a threshold value for sufficient CP to reduce external corrosion to an acceptable rate ( less than 0.001� per year). However, there is a need for an alternative method that more accurately depicts the corrosion rates of buried pipeline.

This document contains instructions for the sampling of steel pipe surfaces for contaminant ions using electrolytic limpet cell extraction or direct contact extraction with chromatographic papers, and analytical test methods for chloride, sulfate, nitrate/nitrite, and ferrous iron ions. The electrolytic limpet cell sampling method is the preferred technique for the recovery of ion contaminants from all pipe surfaces. Contact paper sampling may be used when operating conditions make the use of electrolytic limpet cell sampling impractical or inconvenient. Examples of sampling and analysis data

The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the
