| description | 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 the functional group and the toughness of
PHA chelating resin was FTIR and TGA spectroscopy. Other method that use to
characterize the functional group of the hydroxamic acid is conducted using
qualitative test by observe the colour change of vanadium(V) ion. The chelating
behaviour of PHA chelating resin is observed by conducting batch technique. The
binding capacities of cooper, iron, nickel and zinc were excellent and the nickel
capacity was maximum (0.0164 mmol g⁻¹) at pH 6. The rate of exchange of cooper
was very slow that is h'2 < 10 min. It was also observed that the metal ion sorption
capacities of resin were pH dependent and its selectivity towards the metal ions used
is in the following order: Ne+ > Zn²⁺> Fe³⁺> Cu²⁺. |
