本文应用几种不同的有机高分子材料对消毒剂二氯异氰尿酸钠进行了固定化，测定了固定化后的二氯异氰尿酸钠的释放速率，并对影响释放速率的各种因素进行了初步讨论．实验结果表明，用聚乙烯酸（PVA），聚甲基丙烯酸甲酯（PMMA）和聚丙交酯（PLA）固定化二氯异氰尿酸钠均能达到缓释目的．其包埋量可达64％，缓释周期可控制在4～2000h，固定化后的二氯异氰尿酸钠释放率达99％以上．
In this paper, several different organic macromolecule materials were used to immobilize the disinfectant sodium dichloroisocyanurate. The immobilized sodium dichloroisocyanurate was measured and the various factors affecting the release rate were determined. A preliminary discussion. The experimental results show that the immobilization of sodium dichloroisocyanurate with polyacrylic acid (PVA), polymethylmethacrylate (PMMA) and polylactide (PLA) can achieve the purpose of sustained release. Its embedding capacity can reach 64%, the slow release period can be controlled at 4 ~ 2000h, and the immobilized sodium dichloroisocyanurate release rate reaches more than 99%.
