Investigation of adsorption properties of vermiculite-associated composites in relation to phenol
Adsorption properties of the modified chemical and thermal treatment of vermicuLite by the degree of extraction of phenol from the solution were studied: I composite vermicuLite + 12% HCL + ceLLuLose; II composite - vermicuLite + 12% HCL + ceLLuLose (caLcined at 600-700 ° C); III composite - vermicuLite + 12% HCL + ceLLuLose + 15% NH3 • H2O; IV composite - vermicuLite + 12% HcL + ceLLuLose + 15% NH3 • H2O + (caLcined at 600-700 ° C). It has been discovered that composites I and III are ineffective in the adsorption of phenoL from aqueous soLutions. Sorbents II and IV, caLcined at high temperature, have the best sorption properties as reLated to phenoL.
