Preparation and characteriztion of PHA chelating resin from PMA grafted sago starch

The preparation of poly(hydroxamic acid) (PHA) chelating resin was from polymethyl acrylate(PMA) grafted sago starch. The PMA grafted sago starch was obtain by free radical initiation process in which ceric ammonium nitrate was use as initiator. The instrument that has been use to characterize th...
