在2M NaOH中水解制备亲水性聚丙烯腈（PAN）超滤膜。亲水改性提高了PAN超滤膜分离丹参汤剂的防污性能，稳定渗透通量大，时间短。采用不同亲水性的聚丙烯腈膜进行过滤时，渗透液中丹参素和原儿茶醛的含量和比例不同。其对中草药生产性能的影响有待进一步研究。
Hydrophilic polyacrylonitrile (PAN) ultrafiltration membranes are obtained by hydrolysis reaction in 2M NaOH. Hydrophilic modification improves antifouling property of the studied PAN ultrafiltration membranes in separating Salvia Miltiorrhiza decoction: the large steady permeate flux and the short tssare achieved. The content and ratio of danshensu and protocatechuic aldehyde in the permeates are different when PAN membranes with different hydrophilicities are employed for filtration. Its effect on Chinese herbs performance should be further studied.
