| 摘 要： | 以自制的不同浓度的酸性重铬酸钠溶液为合成废水，利用准液膜法从废水中提取Ｃｒ，并用提取后剩余溶液中Ｃｒ的浓度表征处理效果。结果表明：当废水中铬含量在４００ｍｇ／Ｌ以下时，经一次提取，铬含量在８００ｍｇ／Ｌ时，则需２次提取，提取余液中Ｃｒ的含量均降至５ｍｇ／Ｌ左右；当碱液呈喷雾状下落时，提取效果更好。

| Abstract: | Cr() was extracted from the wastewater by pseudo liquid membrane method,which the wastewater was composed of a variety of concentration of sodium dichromate in acidic aqueous solution. The extracting results were charactered by means of the Cr() in remaining solution. When Cr() was lower than 400 mg\5L\ \{-1\} in the wastewater, extraction for one time, and Cr() was 800 mg\5L\ \{-1\}, extraction for twice ,the results showed that the concentration of Cr() in remaining solution is 5 mg\5L\ \{-1\} or so. As the basic solution sprays falling, the results were well. This method will be pontential to handle industrial wastewater containing Cr().\= |
