Abstract

Abstract: Sulfonic rosin-benzyl-ester polymer(SRBEP) was synthesized from rosin-benzyl-ester polymer and sulphuric acid.The content of—SO₃H in SRBEP was measured,and the structure of the product was analysed by IR.The (adsorption) characteristics for metal ions Co²⁺,Cu²⁺,Pb²⁺ and reusability of SRBEP were discussed.The results showed that:SRBEP could well adsorb Co²⁺,Cu²⁺ and Pb²⁺,especially Co²⁺,Pb²⁺.Relative retention of the resin could be kept over 80% after reusing for 6 times.It could be used for separating and purifying of metal ions.

Key words: sulfonic rosin-benzyl-ester polymer, metal ions adsorption
