摘要
本文用蛋白、聚乙二醇和葡聚糖三种不同溶质对聚砜、聚砜酰胺及磺化聚砜三种超滤膜的截留率—分子量曲线进行了测定。对同一种膜,具有相同分子量的不同溶质来说,它们的截留率是不同的。膜对蛋白的截留率高于它对聚乙二醇和葡聚糖的截留率。
In this paper,the retention-molecular weight relationships of ultrafiltration membranes PS, PSA as well as SPS were determined by means of different test substances proteins, dextrans and polyethylene glycols. The retention of the same molecular weights but different test substances for same membrane is not similar.The retention of proteins is higher than that obtained by glycols and dextrans.
