摘要
用四种不同结构的聚二甲基硅氧烷及其改性有机硅膜分离舍酚废水.研究了分离温度、酚浓度以及不同种类酚对透过速率及分离系数的影响。结果表明聚合物中有机硅成份的含量对透过速率及分离系数均有较大影响。渗透汽化法分离含酚废水是一个有前途的方法。
The sewage containning phenols were disposed by pervaporation membranes,which composed of four polydimethylsilicone and its copolymers. The effect of separa-tion temperature,concentration of phenols and different kinds of phenols onpermeation rate and selectivity was studied. The results showed the contents ofdimethylsilicone in the polymer membrane materials had influence on separation per-formance of membranes. Pervaporalion offers good prospects in the removal of trace phenols from aqueoussolutions.
