Humic composites - sorbents for analysis of river water quality

Abstract

The current state of the problem shows that climate change is accompanied by a certain impact on the basic parameters of human life, among which a special place is occupied by the problem of water resources, their quality, quantity, possibilities of consumption, purification and others. In this regard, much attention is paid to assessing the quality of consumed water, since its use is determined by a number of factors, including: irrational use, pollution (chemical/biological), uneven distribution. A rather complex environmental situation has formed in the Kyrgyz Republic, associated with an increase in the level of man-made pressure on the environment. This influence, in turn, is accompanied by the emergence of new problems of protection and reproduction of geo- and biological resources. To analyze the quality of river water samples of the Alamedin River (spring and autumn samples) were selected, followed by purification with modified humic materials in the form of humic composites containing hybrid nanoparticles of iron oxide and rare earth metals. The purpose of the work is to study the influence of sorption modes on modified humic composites when analyzing water samples from the Alamedin River.
