Vanadium is extensively utilized in a variety of industries, including textiles, chemical manufacturing, metal plating, and many more. Pentavalent Vanadium is a highly toxic and carcinogenic substance when present in high concentrations. Therefore, eliminating it from industrial effluents before it can reach any water supply or land is critical. In the present research, the determination of trace V(V) by Differential pulse polarography (DPP) and its removal from industrial effluents by using Annona squamosa leaves as biosorbent has been analyzed. The mercury electrode is used as working electrode for DPP analysis. The reference and auxiliary electrodes were Ag/AgCl and platinum wire respectively. The biosorbent capacity of Annona squamosa leaves were analyzed by using different parameters like pH, concentration, contact time, biosorbent dosage, and temperature. The V(V) showed a sharp DP peak at -1.19V in presence of Ammonia-Ammonium phosphate buffer. The maximum V(V) adsorption was 8.1mg/g and 85%with respect to contact time and concerning temperature respectively. The present study concluded that the determination of V(V) by DPP are in good agreement with that of results obtained from UV-VIS technique. Further the biosorbent so prepared from Annona squamosa leaves is likely to be a cost-effective, economically feasible, and easily available material for removing V(V)from industrial effluents.
