文摘
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 functional group. The resin has been employed for removal of transition and toxic metal ions from reference aqueous solution and from the underground mine water of the Rajpura Dariba mines, Hindustan Zinc Limited, Udaipur, India.
