Abstract:

Phytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon, and moringa seeds as experimental materials to investigate their potentials as possible blastofiltration materials. The results showed that with the trial time lasting up to 72 hours, lead (Pb) and cadmium (Cd) content in the contaminated water (60ppm in each case) decreased by 96-99%. The removal effects of okra and castor seeds were the most efficient whereas the whole seeds of moringa showed the best removal effects (100%) on cadmium. Plant seeds of less economic importance could represent the next generation green technology at bioremediation of heavy metal polluted water.
