The present study was undertaken to compare the effect of adsorbent dosage and pH on adsorption effectiveness of ZnCl₂-activated pawpaw seeds (ZAPS) and H₃PO₄-activated pawpaw Seeds (HAPS) based granulated activated carbon in removing Malachite Green (MG). The capacity of ZAPS and HAPS adsorbents prepared to adsorb MG from aqueous solution at different pH values (2.0-10.0) and adsorbent dosage (0.50-2.50 g) were monitored using batch mode. The effects of agitation time, adsorbent dosage and pH were examined in each case. The findings shows that at different adsorbent dosages and pH values, ZAPS is a better adsorbent than HAPS.
