Biosorption study of pharmaceutical industry effluent using few aquatic Macrophytes

The study was conducted to treat the Pharmaceutical industry effluent using few dried powered aquatic macrophytes (Lemna minor L., Azolla pinnata L, Pistia stratiotes L. and Ceratophyllum dermasum). The treatment was carried out on various concentrations (25%, 50% 75% and 100%) of Pharmaceutical Industry effluent. Highest removal of pollutant was observed at lower effluent concentrations (25% and 50%) as compare to higher effluent concentrations (75% and 100%). The addition of aquatic macrophytes has brought significant reduction in various parameters of Pharmaceutical industry effluent. The reduction in pollution load may be due to the sanative and adsorptive properties of macrophytes in aquatic system which can be used as low cost and safest biological adsorbents for removing toxic substances in pharmaceutical industry effluent.
