摘要
运用标称孔径为 0 .45μm的聚偏氟乙烯 (PVDF)微孔膜 ,本文对浓度为 2 0 mg/L的 Cr3+水溶液体系进行了减压膜蒸馏实验研究 ,结果表明该膜对 Cr3+具有较好的分离效率和较高的膜通量。
This paper deals with vacuum membrane distillation (VMD) experiments with PVDF microporous membrane, whose nominal pore size is 0.45μm, to separate the Cr 3+ from the original Cr 3+ concentration about 20mg/L. The optimized technical conditions have also been investigated. The results show that high separation effciency and a large flux can be obtained.
