Utilization of Leucaena leucocephala wood char as bioenergy by-product for methylene blue adsorption: Production, characterization and application

Abstract

Leucaena leucocephala wood char (LC) was produced by a pyrolysis process at 1000 °C. The characteristics of char were identified using scanning electron microscopy (SEM), fourier transform infrared (FTIR) spectroscope, ultimate analysis and BET surface area. Adsorption of methylene blue (MB) dye onto produced LC was tested. The maximum MB dye removals were 65.77, 78.48, 86.14, 90.02 and 90.21 % at 0.5, 0.7, 1, 1.2 and 1.4 g of LC dose respectively
