Biosorption of heavy metals by biosorbent mixture of mangrove bark and oil palm mesocarp fiber: kinetics and isotherm studies / Nicodemus Ujih Michael Brenden

The existence of toxic metals in water supply has become a severe issue and created awareness amongst researchers in order to find the significant methods for the removal of toxic metals. This is due to the characteristics of heavy metals that can accumulate in living tissues and cannot be degradable. Currently, people are using traditional method in removing heavy metals; however, this method has the disadvantages in term of cost and not eco-friendliness compared to biomass. In this study, oil palm mesocarp fibre (OPMF) (Elaeis guineensis sp.) and mangrove bark (MB) (Rhizophora apiculate sp.) were used as biosorbent. Both MB and OPMF were chemically treated using 37% Formaldehyde and NaOH, and HNO3 to ensure the better biosorption efficiency
