## D Ñ: 101 苗青, 许家鸾, 王京霞( , 310006) : 研究D 吸附树脂的再生活化工艺 采用正交试验法, 以树脂比吸附量 为参考指标, 考察两种再生液的 101 酸碱浓度(A) , 乙醇浓度( B) , 浸泡时间( C) 三因素对再生效果的影响 优化的D101吸附树脂再生工艺是: 碱性醇为 A B C ; 酸性醇为A B C D 树脂在使用2~ 3 个周期后, 应及时进行再生活化, 先按常规用酸碱水和乙醇洗脱, 再用 2 2 1 3 3 1 101 - 1 - 1 0.05mol#L NaOH 的75% 乙醇溶液和0. 1mol#L HCl 的 0% 乙醇溶液浸泡洗脱 : 吸附树脂; 再生活化; 比吸附量 : R 17; R 27 : B : 1007-76 3( 2004) 02-0152-03 Experimental studies on reuse technology of D adsorption resin: influence of acid concentration, base concen- 101 tration, ethanol concentration and time on reuse MIAO Qing , XU Jia-luan ,WANG Jing-xia( Zhej iang H osp ital of Traditional Chinese Medicine, H angz hou 310006, China) ABST ACT:OBJECTIVE To study reuse technology of D101 adsorption resin. METHOD Using orthogonal test, measuring absorption ration of adsorption resin , study the influence of acid concentration, base concentration(A) , ethanol concentration( B) and extract time( C) on reuse. ESULTS The best reuse technology was: ethanol acidwas A B C , ethanol base was A B C . CONCLUSION After two or three 2 2 1 3 3 1 weeks, D101 adsorption resin must be reused in time. The resin was washed by aqua acid, aque base and ethanol first, then washed by 0. 05mol#L- 1 NaOH-75% ethanol and 0. 1mol#L- 1 HC-l 0% ethanol.
