LANGMUIR ISOTHERM OVER BIOSORPTION CAPACITY OF CADMIUM FROM CACTUS AND BANANA PEELS

Banana peel and cactus an agricultural waste, was used as biosorbent for the biosorption of cadmium ions from aqueous solution. The important parameter such as particle sizes, initial solution pH and initial cadmium ion concentration were evaluated on biosorption studies, in a batch scale at 25oC. Banana peel and cactus peel contains gelatein, which has binding capacity to bind metal ions. The result shows that banana peel and cactus could be used as biosorbent for removing cadmium ions from aqueous solution. A low cost material that shows potential use in wastewater technology for removing of heavy metal.
