Abstract: An efficient separation of the trace Pb(II) in waste water was carried out taking TiO2 nanoparticles as adsorbent and flame atomic absorption spectrophometer as detector to determine the concentration of Pb(II). The effects of the crystalline structure of TiO2 nanoparticles, pH values of solution, adsorbing time and initial concentration of Pb(II) on the adsorption rate were systematically studied, with the optimum adsorption conditions determined, i.e., pH=6.5, m(TiO2)=20 mg, ρ0(Pb(II))=18 mg·L-1, t=90 min. The relevant adsorption isotherm was then determined with the isotherm equation given on the basis of Freundlich formula.
