back extraction

基本解释

Results show that the mixed solvent can give high distribution extraction rate for acetic acid wastewater. Back extraction rate was 98. 4%.
试验结果表明：混合溶剂对废水中的醋酸有较高的萃取率，反萃取效果为98.4％。
Meanwhile, a new back extraction technology suitable for the continuous application of CPE was developed based on the reverse micelle phenomenon.
同时，基于反胶束技术开发了适用于连续CPE处理过程的新型CPE反萃取工艺。
The effects of acidity, Cl- concentration, extraction stages and the conditions of back extraction on the recovery efficiency of Co and Ni have been studied.
重点研究了酸度、氯离子浓度、萃取级数及反萃条件对钴镍分离效率的影响。
