摘要

Removing lead ion in aqueous solution using petai (Parkia speciosa) residue was done well. Petai residue is modified with sodium hydroxide and sulfuric acid before batch adsorption process occured. The results showed that the highest adsorption capacity was found in acid modification that was 2.62 mg/g.Temkin and Dubininmodels fit the adsorption isotherms of all adsorbents.
