Phytoremediation is a new technology in which plants are used to remove pollutants from water and
soil. Interaction between plants and heavy metals is based on the ability of plants to absorb and
accumulate metals from soil. FTIR spectra also confirmed the interaction of chromium ions with the
hydroxyl, carboxyl and amino groups that are present on the plant biomass used for phytoremediation
of tannery effluent. The high removal efficiency and heavy chromium accumulation capacity of Hyptis
suaveolens makes an excellent choice for phytoremediation of tannery effluent. The Atomic Absorption
Spectrophotometric (AAS) analysis of tannery wastewater revealed that the samples were heavily
contaminated with heavy metals, mainly with chromium. The roots of Hyptis suaveolens accumulated
more heavy metals than the stem and leaves. The experiment results that the Hyptis suaveolens can be
used for removal of heavy metal from tannery contaminated soil.
