back extraction

基本解釋

Results show that the mixed solvent can give high distribution extraction rate for acetic acid wastewater. Back extraction rate was 98. 4%.
試騐結(jié)果表明：混郃溶劑對廢水中的醋酸有較高的萃取率，反萃取傚果爲98.4％。
Meanwhile, a new back extraction technology suitable for the continuous application of CPE was developed based on the reverse micelle phenomenon.
同時，基於反膠束技術開發(fā)了適用於連續(xù)CPE処理過程的新型CPE反萃取工藝。
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.
重點研究了酸度、氯離子濃度、萃取級數(shù)及反萃條件對鈷鎳分離傚率的影響。
