Chemical activation of dispersed silica-flask
Abstract
Chemical activation of dispersed silica-flask
Incoming article date: 27.02.2019The differential thermal analysis (DTA) necessary for the study of structural changes in dispersed silica – flask occurring at elevated temperatures is carried out. A comparative analysis of the results of electromicroscopic studies, showing the dependence of the structure of the surface of the flask on the temperature treatment. It is considered that the defining characteristic of the natural sorbent-flask in the process of wastewater treatment is its specific surface area and porous structure. The influence of calcination temperatures on the adsorption properties of the natural mineral – flask is considered.
