Pervaporation Characteristics of Removal of Trace Phenol in Aqueous Phenol Solution Using Tubular Type PDMS/Ceramic Composite Membrane

홍연기, 김용운, 홍원희

초록

적절한 선택도를 유지하면서 투과도를 향상시키기 위해 기존의 실리콘(PDMS)막을 세라믹 지지체에 코팅한 복합막을 사용하여 페놀 수용액에 대한 투과증발 실험을 수행하였다. 수용상에서의 잔류 페놀에 대한 투과증발 실험에서 페놀의 선택도는 공급액에서늬 페놀의 농도에 따라 감소했으며 투과량은 증가하였다. 또한 선택도는 조업온도가 증가함에 따라 증가하는 것으로 나타났다. 이러한 현상들은 공급액이 가지는 투과도의 차이와 수착에 따르는 막의 가소화 그리고 지지체 세공에서의 물의 모세관 응축으로서 설명이 가능하다.

PDMS(Polydimethylsiloxane)/ceramic composite membrane was used in pervaporation process in order to enhance the flus with maintaining proper selectivity. In Pervaporation of trace phenol from aqueos phenol solution, selectivities of phenol decreased and fluxes increased with concentration of phenol in feed mixtures. And selectivities of phenol increased with operating temperature. This phenomenon could be explained by coupling of each components, plasticization of PDMS membrane, and capillary condensation of water in ceramic pores.
