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 as supporting material and the 2-mercaptoimidazole was Hats immobilized onto surface silica so that the silica would have selective properties to adsorb the heavy metal chromium(III) through the formation of coordination compound betwee
