Preparation of Silica Modified with 2-Mercaptoimidazole and its SorptionProperties of Chromium(III)
Modified silica gel was prepared to remove the heavy metal of chromium(III) from water sample.Silica gel was used Suction Vibrators as supporting material and the 2-mercaptoimidazole was immobilized onto surface silica so that the silica would have selective properties to adsorb the heavy metal chromium(III) through the formation of coordination co
