摘要
Abstract
Pyruvate ehitosam (PCTS) was successfully prepared from chitosan and pyruvic acid, after reductived by NaBH4. The structure of PCTS was determined by IR adsorption, field emission scanning electron microscopy and elements. The results show that the best synthesis condition is, the reaction time 4.5 h, pH 4.5, pyruvic acid with chitosan ami no mole ratio on 2:1 for the substitution degree 90.6%; 1.67 g/L PCTS adsorbed 30 mL 10 μg/ mL of the Pb2+ at pH 5.4 for 2 h, achieved adsorption equilibrium, the maximum adsorption is 27.1 mg/g, better than chitosan.关键词
