Synthesis and application of chemically modified tamarind based TTPCA resin for removal of toxic metals from industrial effluents

Abstract

TKP (Tamarind Kernel Powder) and its chemically modified derivatives are important biosorbents for removal of heavy metals such as lead, cadmium, iron, zinc, and copper from industrial effluents. TKP falls in natural gums category polymer which is completely non- toxic, bio-compatible and bio-degradable natural polymer. It has a hydrophilic polysaccharide matrix, which have been used for the synthesis of chelating resins. In present investigation a new Tamarind Kernel Powder based chelating resin {named as TTPCA) containing Proline group has been synthesized. Hear Proline group has been incorporated into TKP with the help of cyanuric chloride in the presence of dioxane medium. TKP resin serves the purpose of both flocculants as well as selective ion binders for heavy metals. This resin is totally eco-friendly and also supports green chemistry.
