Insights on phytoremediation of chromium from tannery wastewater contaminated soil.

The study was conducted to evaluate the phytoremediation response of and vetiver grasses irrigated by different levels (0%, 10%, 25%, 50%, 75%, and 100%) of treated tannery wastewater. After 60 days, matured plants were harvested, sorted into root, leaf, stem and shoot, dried and digested using standard procedures and analyzed for Cr(VI) and total Cr using atomic absorption and UV-Visible spectrophotometer, respectively. Corresponding results revealed height growth of and vetiver grasses was greatly affected by the irrigation level of tannery wastewater.
