| 摘 要： | 采用络合剂乙二胺四乙酸（EDTA）二钠和硅烷偶联剂KH-550对磁性Fe3O3粒子进行表面修饰改性，并用其对天然胶乳中的蛋白质进行吸附分离。结果表明，EDTA通过化学键合牢固地结合在粒子表面，并通过羰基与蛋白质反应，达到降低胶乳氮含量的目的。

| Abstract: | Modification of Fe3 O4 with EDTA and KH -550 were carried out ,and the effects on the nitrogen content of NR latex were also investigated on this paper. The results showed that, EDTA was linked to the surface of Fe3O4 by chemical bond,and the nitrogen content of NR latex was reduced by adding EDTA modified Fe3O4. |
