Performance evaluation of Cr (VI) removal by using activated carbon and water hyacinth

In the present investigation, the scope of commercially available powdered activatedcarbon (adsorbent) and water hyacinth (absorbent) as alternative cost-effective and efficient treatment methodologies have been warranted for a simulated aqueous environment. Thepresent sorption studies were carried out in the batch reactors under control conditions such as contact time, pH, initial adsorbent concentration and adsorbent dosage. While water hyacinth as an absorption media indicated economic viability, isotherm analysis indicated adsorption by activated carbon as an excellent alternative and reliable technique forCr (VI) removal.
