To develop a methodology for the removal of a Toxic dye Rhodamine B (RB) from aqueous solution by using low cost, rapid, economical and biodegradable, natural material Spirulinaplatensis (SP) Employing the batch extraction method. The component of like saccharides, fat and vitamins containing functional group like carboxylic group which attract the positive charge of dye by electrostatic interaction with pollutant and water hazardous pollutant. The presence of dyes in water bodies act as

... nt and cause hazardous effect on natural resources, aquatic life as well as to human being. The interaction of dye with Spirulinaplatensis was investigated as a function of pH of the aqueous solution of the dye, contact time for batch extraction and the initial concentration of the dye in aqueous solution. We have also explored the efficiency of these for removal of suspended solids in water separation in a single step. Highest 62.13% uptake efficiency recorded was for 60 mg/L of 25 mL solution concentration onto 25mg of Spirulinaplatensis.
