A sulphonic acid group has been incorporated in guaran or galactomannan polysaccharide in order to develop a hydrophilic flocculant cum cation exchanger. Cis-hydroxyl groups present in the guaran matrix help flocculating the metal ions along with their cation exchange by the sulphonic acid functiona
