ZINC AND CHROMIUM REMOVAL MECHANISMS FROM INDUSTRIAL WASTEWATER BY WATER HYACINTH, EICHHORNIA CRASSIPES (MART.) SOLMS
2012
Applied Ecology and Environmental Research
Zinc and chromium are environmental pollutants that are toxic even at very low concentrations. Domestic and industrial wastewater discharges are probably the two most important sources for chromium and zinc in water.
