Potential of Leucaena Leucocephala pod and pineapple leaf as biosorbent

Low-cost adsorbent adsorptions were carried out by different agricultural wastes that are Leucaena Leucocephala (LL) and pineapple leaf. Methylene Blue (MB) is used to determine the adsorption of MB onto agricultural waste and removal of MB in the adsorbents. The objective of this study is to study the characterization of LL and pineapple. Analysis for characterization that has been done for this study is TGA, FTIR and UV-Vis Spectrophotometer. From the results, it shown that LL has higher percentage removal of efficiency (R%) which are 65% and 58% for pineapple leaf. From the results of FTIR, both agricultural wastes contained functional group that help to ease the adsorption process such as N-H group, C-O-C group, C=C group and O-H group. LL has low contained of lignin while pineapple has lignin content in the structure. From this study, it can be proved that LL and pineapple can be the biosorbents.
