Technology of Waste Waters Purification Using Natural Sorbents Based on Humic Materials Derived from Brown Coals

摘要

The prevention of pollution of water basins by waste waters is of great importance for national economy. Therefore, studies aimed to develop efficient and economically grounded technologies of waste water treatment are of great significance nowadays. To solve such environmental tasks, producing absorbents on the base of brown coals containing humic acids up to 70% are very promising. Humic acids are referred to weak acid polyelectrolytes and possess properties of sorbents, filtrants, ion-exchange materials, flocculants. By means of purposeful modification natural properties of coals may be enhanced.
