新型高效吸附剂SA-1的合成

Synthesis of Higher Adsorptives Ability Adsorbent

以硫酸铝和硅溶胶为原料采用共沉淀法制备硅酸铝类高性能吸附剂,用于蛋白酶类生物活性物质的提取。在反应温度30～35℃,晶化时间为10h,水洗达到SO42-浓度1.0%,经共沉淀、晶化、水洗、喷雾干燥等工序可以制得Al2O3xSiO2yH2O吸附剂,该吸附剂用于人绒毛膜促性腺激素(HCG)的提取,提取回收率达到95.5%和粗品HCG的比活性可以达到900IU/mg。

Higher adsorptives ability adsorbent for human chorionic gonadotropin was prepared from Aluminium sulfate and silicasol,under temperature 30～35 ℃,in 10 h.The adsorbent recovery rate was over 95.5 % as adsorbent of human chorionic gonadotropin（HCG）,and HCG activity was over 900 IU/mg.
