Structure And Sorption Properties

The sorbent with the grafted layers of malonate copper was obtained on the surface of silica gel Silokhrom S-120 by the method of successive assemblies. Structural, sorption and chromatographic properties of the investigated materials were studied by adsorption of porosimetry, gas chromatography, pH-measurement and Hammett’s method. The sorbent was used for solid phase extraction of organic compounds from aqueous solutions.
