In this paper, gentian violet as template molecule, acrylic acid (AA) as the monomer, N,N’-methylene double acrylamide (MBA) as crosslinking agent, azodiisobutyronitrile (AIBN) as initiator, acetonitrile as the pore system, gentian violet molecularly imprinted polymer (GV-MIP) was prepared by bulk polymerization method. The adsorption capacity of Cr(III) by GV-MIP at different concentrations and temperatures were studied and compared with the non-imprinted polymer (NMIP) and Cr(III) imprinted polymer (Cr-MIP). We found that the adsorption capacity of GV-MIP for Cr(III) is significantly higher than NMIP and Cr-MIP, and increased with the concentration of Cr(III). The maximum adsorption capacity is 126.16 mg/g, and the optimal temperature is 25˚C.
