Abstract:
The indiscriminate release of toxic heavy metals (HMs) such as lead (Pb) in to surface/ground water has
led to several serious environmental problems. In this research, the potential of Pomegranate seed
powder (PSP) was evaluated as a natural adsorbent for Pb removal from contaminated water. Real
samples of contaminated water from Babol River were used to evaluate the performance of PSP. The
effect of main operation parameters such as PSP dosage, contact time, initial concentration of HMs and
pH on removal efficiency were studied. Moreover, SEM, EDX and FTIR analyses were performed to
investigate HMs removal mechanism. According to the results, adding ۱.۵ g/L of PSP to samples could
increase the removal efficiencies of Pb to ۸۸% within ۳۰ min contact time. Initial concentrations of Pb
and pH variation showed negative effect on Pb removal. The results of SEM-EDX and FTIR analyses
revealed that PSP has good feature which can effectively adsorb HMs through physico-chemical
mechanisms. This study suggests HMs removal by PSP as a promising approach for heavy metals
removal from contaminated surface water.
