Abstract: This study evaluates the effect of preparation conditions for the production of eco-friendly composite adsorbent for the removal of COD, colour and Cu(II) from actual textile effluent by adsorption. The composite adsorbent was prepared by determining the optimum ratio of limestone powder (LP) and palm shell activated carbon (CSAC) as the precursors. Viscous gum (AG) which was extracted from brown seaweed (Laminaria digitata) was mixed with the precursors during the adsorbent preparation as the binding agent. From laboratory experimental and statistical analysis, the preparation condition of the composite adsorbent indicated that the models developed for COD, colour and Cu(II) removals showed higher coefficient of determination with more than 94% which reflects good agreement between calculated and the observed results. The findings also demonstrated that CSAC, LP and AG dosage had significant relationship towards parameters removal when tested with three dimensional plots. The optimization procedure revealed that 7 g CSAC, 3 g LP and alginate binder ratio of 2.49% (w/v) were the best preparation condition that could remove 81.10%, 83.60% and 79.50% of COD, colour and Cu(II), respectively.
