摘要
研究了藻朊酸、藻朊酸钠及二价金属离子交联的藻朊酸钠膜对水／乙醇体系的渗透汽化性能同时，还研究了藻朊酸盐膜对水／甲醇、水／异丙醇、水／丙三醇、水／丙酮体系的分离性能结果表明。
In this paper, the pervaporation characteristics of water/ethanol mixture through alginic acid membrane, sodium alginate membrane and sodium alginate membrane crosslinked by divalent metal ions were studied. The separation properties of alginate membrane toward water/methanol, water/iso-propanol,water/glycerin and water/acetone mixtures have been studied. It was found that alginate membrane could separate these mixtures effectively.
