The characterization of synthetic active carbons as a sorbent for solid phase extraction

Abstract

A correlative study between the physical properties and the adsorptive/desorptive properties of four activated carbons (RG1, RB-T, ROW and CG) for solid phase extraction (SPE) of phenols was carried out. In determining the adsorptive properties, a few differences were found between the distribution coefficients (K-D) and breakthrough volumes, which were attributed to the different physico-chemical properties of activated carbons. For phenol and chlorophenols, methylene chloride was the best desorbing solvent, but for other phenols, acetonitrile was the best solvent on an average.
