Abstract
A few cellulose derivatives were prepared by the reaction of chlorodeoxycellulose (CDC) with ethylenediamine (ED), thiourea, thiosemicarbazide, thioacetamide, and others. These derivatives were found to be able to remove mercuric ions to an extent greater than 99% from a 10 ppm aqueous solution of mercuric chloride. For example, thiocellulose obtained by reacting CDC with thiourea and subsequently hydrolyzing it showed such good removal in the batch and continuous removal tests which involved passing the solution through a column packed with this cellulose derivatives.

Three polystyrene (PS)-polyoxyethylene (POE) block copolymers were synthesized: S114 and S123 as copolymers of POE-F'S-POE type, and 561-10 as that of +PS-X-PO& X+ type. Although the copolymers themselves did not remove nonionic surfactant, polyethylene glycol mono-p-nonylphenyl ether (NP, n = lo),
