Problems solved by technology

Adsorption materials have the characteristics of selective adsorption of water pollutants. Activated carbon and expanded graphite have a good adsorption effect on organic matter in water, but the adsorption effect on heavy metal ions in water is not good; inorganic materials such as clay minerals and zeolites have a high removal rate of heavy metal ions in water. For some organic substances in water, the adsorption performance may be poor

Abstract

The invention discloses a novel adsorption composite material, prepared from the following substances in parts by weight: 30-45 parts of activated carbon, 25-35 parts of ion exchange resin, 8-12 parts of aliphatic epoxy resin, 7-13 parts of glycerophosphate, 10-15 parts of phosphopyridoxal, 11-16 parts of 4-chloro-2-aminophenol-6-sulfonic acid, 4-7 parts of 2,6-dimethoxyphenol, 8-12 parts of 3,4-dimethoxybenzyl alcohol and 15-20 parts of diethylene glycol monobutyl ether. Through mixing the modified activated carbon with the modified ion exchange resin, the composite material with good adsorption effects on heavy metal ions as well as chemical organic matters is prepared.

Description

technical field [0001] The invention belongs to the technical field of composite materials, in particular to a novel adsorption composite material and a preparation method thereof. Background technique [0002] With the rapid development of industrialization and urbanization, the problem of water pollution has become the focus of people's increasing discussion, especially the pollution of drinking water, which people pay close attention to. The number and types of chemical organic matter and heavy metal components in drinking water are increasing, and various pathogenic microbial factors are also emerging. my country also has more than 60% of the population drinking water that does not meet the drinking water quality standards. Therefore, the removal of trace pollutants and heavy metals in drinking water has become an important task for water purification. [0003] At present, advanced drinking water purification technologies used in the prior art include: membrane separat...
