- Abstract
The massive growth of aquatic plants can contribute to the problem of biological pollution; however, these plants can be utilized to solve other environmental issues. There are plants noted to have a contribution to the adsorption of heavy metals. This study investigated the biosorption capacity of selected aquatic plants. The biosorption of Pb2+ was tested using pulverized water lettuce (Pistia stratiotes (L.)), water hyacinth (Eichhornia crassipes), and water spinach (Ipomoea aquatica). The increase in biosorbent doses under laboratory conditions at 24 h of contact time has a moderate influence on the pH of the aqueous solution. Metal ion adsorptions were strongly dependent on pH, with an optimum pH of 4-5. The maximum adsorption capacity (qe) of Pb2+ was 3.62, 2.31, and 3.52 mg g-1 using water lettuce, water hyacinth, and water spinach. The biosorption efficiency of the aquatic plants is moderately influenced by the biosorbent doses, with a maximum efficiency of 99.99 %.
