Popis: | The adsorption of Pb (II) ions from aqueous solution by bio adsorbent from jackfruit wood sawdust treated with phosphoric acid was studied in a batch adsorption system. Characteristics of bio adsorbent investigated by Fourier transform infrared (FTIR). The functional group which involved in Pb (II) binding during adsorption process were amine N-H, amide C=O, alkyl C-H, and nitrile C≡N. The effects of phosphoric acid ratio to distilled water and soaking time on the adsorption capacity were investigated. Maximum adsorption of Pb (II) ions was carried out by bio adsorbent which modified by phosphoric acid with ratio to water 0.33. The experiment data of Pb (II) adsorption correlated well with pseudo second order kinetic model with correlation coefficient value 0.9988 and resulted adsorption capacity at equilibrium 1.4382 mg/g. |
