Removal of methyl orange by systems of chloromethylated polystyrene–polyethylenepolyamines and –polyethyleneimines



A study was made of the removal of methyl orange (MO) solutes in water by the reaction products of chloromethylated divinylbenzene crosslinked polystyrene (CMPS) with polyeth-ylenepolyamines (PEPA), polyethyleneimines (PEI), and 2-methyl-2-oxazoline (MeOZO). This behavior of such polymers in regard to the Klotz equation and Freundlich adsorption formula was also examined and noted to conform better to the former than to the latter. The constants of the Klotz equation were calculated. The amounts of MO removed with unit masses of the polymers and the effects of salts on removal were studied. A possible mechanism for removal is discussed.
