KINETIKA ADSORPSI AMMONIUM DARI KOPOLIMER SELULOSA JERAMI PADI DENGAN ASAM AKRILAT DAN AKRILAMIDA

Abstract

Copolymerization  of  cellulose  from  rice  straw  with  acrylic  acid  and  acrylamide produce  biodegradable  superabsorbent  Copolymerization  was  carried out  at  65  C under nitrogen athmosphere.  Initiator and cross linking agent  used were potassium peroxodisulfate  and  N'N-methylene  bis  acrylamide.  Superabsorbent  produced  is anionic,  that  can  bind  ammonium  cation.  The  kinetics  of  swelling  adsorption  was following pseudo second-order equation.
