Morphology and Sorption Characteristics of Surface-Modified Granular Foam Silicate
摘要
Abstract
The paper presents the results of a study of the porous structure and sorption characteristics of technogenic foam silicate obtained in the process of complex processing of waste ore raw materials and modified in the process of thermochemical treatment in the gas phase of hydrocarbons. The parameters of thermochemical modification of the surface of foam silicate to obtain an oleophilic adsorbent for the removing of petroleum products from aqueous media, as well as the modes of its regeneration, have been determined. It has been established that the degree of extraction of petroleum products from water by the resulting adsorbent under static conditions is 99.8%.
