Abstract

Development of new economically feasible eco-friendly products from natural plants/agricultural wastes for removal of pollutants from coastal aquaculture systems is the objective of our continued research. In the present study, attempts have been made to harness lignocellulosic agricultural waste material (bagasse) for the removal of chromium (VI) from highly saline coastal water used for aquacultural practices using brackish water. Five different products prepared from bagasse were evaluated for the detoxification of Cr(VI) from high saline coastal water. The maximum removal capacity for Cr (VI) was found for the material charred with sulphuric acid. Dried bagasse powder was the second most effective product. These substrates are efficient for Cr removal from coastal water owing to their very low cost.
