Phytoremediation of Aqueous Solution Containing Direct Black E Dye with Hydrilla verticillata

Phytoremediation refers to a set of technologies that use different plants as a containment technique. This technology is receiving attention lately. As the results from field trials, it indicates that it is a cost saving technique compared to conventional treatment. The present investigation has helped to understand about the phytoremediation capacity of Hydrilla verticillata to remove colour from the aqueous dye solution. The colour has been completely removed from 10 and 20 ppm aqueous Direct Black E solution after 96 hrs, and from 50 ppm solution after 5 days. Thus, the study helps us to understand the possibility of bioremediation of dyeing industry effluent using Hydrilla verticillata. The recycling and reuse of Direct dye containing dyeing industry effluents would be possible in the days to come.
