Selective adsorption and separation of dyes from aqueous

Introduction In 1896 Beijerinck first noted an incompatibility in solutions of agar a water-soluble polymer with soluble starch or gelatine Upon mixing they separated into two immiscible phases Subsequent investigation led to the determination of many other aqueous biphasic systems of which the polyethylene glycol PEG - dextran system is the most extensively studied
