摘要：
The aim of this research was to investigate the sorption characteristics of polyaniline/sawdust (PAn/SD) for the removal of Zn(II) ions from aqueous solutions. Batch sorption studies were carried out to determine the effect of initial concentration of the sorbate, agitation time, adsorbent dose, and pH on the removal of Zn(II). The sorptive removal was found to be strongly pH-dependent. The experimental data fitted well to the Freundlich isotherm. The products were investigated in terms of morphology and chemical structure by using scanning electron microscopy and Fourier-transform infrared spectroscopy, respectively. Also, PAn/SD was used for the removal of heavy metals from urban waste water. J. VINYL ADDIT. TECHNOL., 17:138-145, 2011. (C) 2011 Society of Plastics Engineers
