摘 要：
To extract heparin sodium,the adsorption effects of heparin sodium by several macroporous resins were investigated and the D208 macroporous resin was chosen as the best experimental material.Based on the single factor experiments and the orthogonal experiment optimization,the optimal conditions of D208 macroporous resin for the absorption of heparin sodium were 0.5 mol·L-1 of salt concentration,5 h of adsorption time,45 ℃ of the adsorption temperature,8.5 of the pH value.The titer of final extracted heparin sodium was 100 U·mg-1.
