羧基化改性玻璃纤维增强不饱和聚酯树脂粉体对铜离子的吸附性能

Cu2+Adsorption Properties of Glass Fiber Reinforced UPR Powders by Surface Modification of Carboxylation

引入相转移剂提高水解改性废弃玻璃纤维增强不饱和聚酯树脂(GFRUPR)粉体的表面羧基含量,制备了羧基含量达26.39μmol/g的GFRUPR粉体,系统考察了溶液pH值、初始Cu^(2+)质量浓度、接触时间和温度对该水解GFRUPR粉体吸附Cu^(2+)性能的影响.结果表明:该水解GFRUPR粉体对Cu^(2+)的吸附量可达20.13mg/g,其还具有良好的再生性能,可循环使用.该研究拓展了废弃玻璃钢粉体的回用途径,在工业废水处理中具有一定的应用价值和前景.

Glass fiber reinforced unsaturated polyester resin（GFRUPR）powders with content of carboxyl group 26.39μmol/g on its surface was prepared by hydrolysis process under the action of phase transfer catalyst.The effects of pH values,initial Cu^（2＋） mass concentration,contact time and temperature on the Cu^（2＋） adsorption behaviors of the hydrolyzed GFRUPR powders were investigated.The results indicated that the adsorption capacity of the hydrolyzed GFRUPR powders was 20.13 mg/g.Moreover,the hydrolyzed GFRUPR powders have good regeneration capacity and reusability.The modification of GFRUPR by functional carboxyl group is a new method for its recycling,and its product may find a certain value and prospects in industry wastewater treatment.
