Cattail plant is a common sight in fresh water wetland, its abundance suggests a potential to be used as a low cost biosorbent for the removal of heavy metal ions. The effect of leaf length on the adsorption of Cu(Il) ions from aqueous solution by dried cattail leaf was studied via batch adsorption studies. It was found that shorter leaf length performed better than longer leaf length in terms of faster adsorption rate and adsorption capacity. the maximum adsorption capacity for the leaf length 5, 10, 15, 20 and 25 mm were 8.92, 8.65, 7.38, 7.03 and 6.66 mg/g, respectively. The adsorption behaviour of the dried cattail leaf-Cu(Il) ions batch adsorption system was best described by Langmuir adsorption model and Bangham kinetic model where the adsorption of Cu(II) ions occurred in monolayer and pore diffusion was one of the adsorption rate controlling steps due to the hollow structure of the dried cattail leaf. The finding of this work suggests that batch adsorption study should be conducted utilising grounded cattail leaf as the adsorbent in order to ascertain the role of chemisorption.
