A Review on Biosorptive Nature of Food Dyes in Lemna minor from Polluted Freshwater Samples

Biosorption is a physio-chemical process that is performed by absorption of substance by microbial biomass. It is passive and reversible process based on the variety of mechanisms like Absorption, Adsorption, ion exchange, surface complexation and precipitation. Biosorption also has a faster rate and produces higher concentrations. Biosorption also has wider applications like mining, metal plating. Phytoremediation is the process that uses the plants to extract and remove elemental pollutants in soil. Dyes are colourful substance that is available in liquid, powder, gel, or paste. In this article, using different variety of food dyes to determine the absorbance of Lemna minor plant by spectrophotometric analysis.
