挥发性有机物的膜回收特性及膜力学性能变化
Studies on extraction characteristics of volatile organic compounds and mechanical properties change with methyl silicone rubber membrane
摘要
Abstract
Macroscopic property of materials has connection with its microstructure.Three kinds of organic matters,which commonly found in high salinity wastewater,and ten kinds of structural parameters were selected to analyze the relationship between structural parameters and the extraction efficiency of these organic matters in the methyl silicone rubber membrane.Mechanical propertiy change of methyl silicone rubber membrane under the factors was researched as well as.Results showed that octanol-water partition coefficient and molecular polarizability of organic matter were the main factors in the methyl silicon rubber membrane.Research on mechanical properties change of methyl silicone rubber membrane suggested that the influence of acidity was greater than temperature and salinity.The mechanical behavior and retention extent of Na+ still could meet the requirements of membrane after 40 days.The methyl silicone rubber membrane has advantages of long life and low replacement frequency.关键词
