摘要
Abstract
Surface modified hydroxyapatite particles were immobilized onto PET filter fabric via heat fusion method. The influence of esterified modification with methacrylic acid or graft polymerized modification with methyl methacrylate on the immobilization was investigated comparing to pristine hydroxyapatite particles. The effects of treating temperature , time and particle amount on immobilization ratio and pore size ratio of hydroxyapatite-immobilized PET filter fabric using different modification methods were discussed and the adsorption property towards heavy metals was evaluated by cadmium adsorption test. The results showed that higher immobilization ratio , pore size and cadmium adsorption capacity of PET filter fabric were achieved by immobilization of graft modified HAp particles than esterified and pristine HAp particles.关键词
