摘要：Epipremnum aureum (L.) Engl. plant has been used for the removal of arsenic and lead from water. Equally sized plants have been grown in the solutions of arsenic and lead separately with different concentrations. Removal of the contaminants has been checked by analyzing samples of water after fixed time intervals. Plots of concentration of pollutants versus time have been drawn to investigate the purification time up to safe limit. The sustainability of plants in different concentrations of pollutants has also been noted. Accumulation of arsenic in different parts of plant (stem, root and leaves) has been determined by digesting the parts separately and estimating the amounts of pollutant in the extracts of plant. In the light of experimental results, a prototype plant has been suggested for the purification of drinking water which can not only be used to remove the dissolved ionic contaminants but also the turbidity and microbes from water. Rate of flow of water has been adjusted in the light of retention time necessary for purification.
