Parametric and adsorption kinetic studies of Methylene blue removal from Aqueous Solution using Bornean Rambutan (Nephelium lappaceum L.)skin
In this study, methylene blue (MB) dye removal from water sample by adsorption onto rambutan skin, was examined. The adsorption studies using batch experiments were carried out under different parametric conditions of initial dye concentrations(3.0 mg/l – 15.0 mg/l), solution pH 2 – 12 and solution...
