摘要
选用美国TriSep公司TS80纳滤膜 ,在操作压力 0 .7MPa下考察了纳滤膜对有机物的截留机理 .TS80纳滤膜对TOC的平均去除率为 90 .3% ,根据色谱质谱联机分析结果可知 ,TS80纳滤膜能使色谱质谱峰丰度降低 50 %左右 ,其对有机物的去除是由有机物的结构特征 (如分子量、极性 )与有机物同膜间的相互作用关系共同决定的 .
A study evaluated organics rejection mechanism by TriSep company's TS80 nanofiltration membrane at 0.7?MPa operating pressure. The average removal of TOC is 90.3%. The GC/MS results indicates that TS80 nanofiltration membrane may reduce approximately 50% abundance and the organic rejection by TS80 is determined by it's structure characteristics(e.g., molecular weight, polarity) and the interaction between organics and membranes.
