Abstract: The article deals with the separation of stable «water in oil» emulsions in a coalescing filter packed with cellulose. The efficiency of the process of separation of the emulsion in the reactor packed with cotton is studied. Based on the experimental results and the literature data the mechanism of separation, as well as its relation to the structure of cellulose molecules are discussed.

Abstract: The article is devoted to the determination of perrenate anion in real samples of solutions obtained by situ leaching, using voltammetry at the electrolyte-electrolyte boundary and electrode amperometric batch. Ways to overcome the effect of various confounding factors, such as the presence of molybdenum, low pH samples, and high iron content are considered. Based on this study a method for determining the concentration of friction in real industrial solutions was compiled and metrologically certified.

Abstract: Electrochemical (voltammetric) analysis at the interface of two insoluble electrolytes can significantly extend the possibilities of today’s analytical chemistry. Of special interest is the possibility of analyzing such ordinary objects as poli-alkil-guanidines, the prospect of which is attractive alternative to chlorination for easy cleaning. A significant advantage of the method in this case is not only the simplicity of equipment, and its assimilation, which is especially important for water quality control in water treatment. An additional advantage is the possibility to determine heavy metals in water using the same equipment, as well as its low cost compared with the complex chromatographic systems sometimes used to solve similar problems.
