摘要:Sulfuric acid treated Petai belalang(Leucaena leucocephala) leaf powder(SLLP) was used as an adsorbent for Pb(II) ions removal.The experimental adsorption parameters investigated include p H,dosage and initial Pb(II) concentration.Pb(II) removal was more favored at a higher adsorbent dosage,p H and temperature.Adsorption kinetics conformed to the pseudo-second order model while Langmuir isotherm model recorded the value of maximum adsorption capacity(qmax) of 222 mg/g.The major functional groups involved in the adsorption process were identified as hydroxyl,amino and ether as revealed by the FTIR analysis.The prepared adsorbent demonstrated a potential application for efficient removal of Pb(II) ions from industrial wastewater.
