Remediation of chromium and copper on water hyacinth (E. crassipes) shoot powder

Tannery effluent characterization and removal efficiency of Chromium (Cr) and Copper (Cu) on water hyacinth has been observed by filtration process. The effluent was contaminated by deep blue color, acidic pH, higher value of total dissolve solid (TDS), electrical conductivity (EC), chemical oxygen demand (COD) and lower value of dissolve oxygen (DO). After filtration, the effluent shows that the permissible limit of investigated metals. Adsorbent capacity of water hyacinth shoot powder for Cr and Cu ion was found to be 99.98% and 99.96% for standard solution (SS) and 98.83% and 99.59% for tannery effluent (TE), respectively.
