Methylene Blue Adsorption onto NaOH Treated Leucaena leucocephala Leaf Power

Abstract:

The potential of sodium hydroxide (NaOH) modified Petai Belalang (Leucaena leucocephala) leaf powder as a biosorbent for methylene blue removal from aqueous solutions was investigated. Adsorption parameters studied include initial dye concentration, pH, dosage, kinetics and isotherms. The pH_zpc of chemically treated Leucaena leucocephala leaf powder was 7.50 and adsorption equilibrium time was achieved after 60 min. The kinetic data was best represented by the pseudo-second order model. The maximum adsorption capacity predicted from Langmuir model was 208.33 mg g^-1. This work indicated that NaOH treated Leucaena leucocephala leaf powder can be an attractive biosorbent for MB removal from diluted industrial wastewater.
