Non-Linear Kinetic and Isotherm Modeling on the Adsorption of Lead (II) Ions from Aqueous Solution onto Monosodium Glutamate Functionalised Rubber Leaf Powder

In order to enhance its cationic sorption capacity, untreated rubber leaf powder (RLP) was functionalized using monosodium glutamate to produce potentially biodegradable cationic sorbent.

Description
Summary:In order to enhance its cationic sorption capacity, untreated rubber leaf powder (RLP) was functionalized using monosodium glutamate to produce potentially biodegradable cationic sorbent. The sorption behaviors of monosodium glutamate functionalised (MGRL) against Pb (II) in a batch system are investigated. The effects of various experimental parameters (e.g. initial pH, contact time) were investigated and the sorption kinetic was elucidated. The Pb (II) removal on MGRL increased as the initial pH increased. The effect of contact time revealed that the equilibrium is reached at 90 minutes. The Pb (II) sorption process on MGRL followed the pseudo-first-order rate kinetics. The Langmuir isotherm model with a maximum adsorption capacity of 109.953 mg/g was found suited to describe the adsorption process.
