摘　　要：用N910从氨/氯化铵水溶液中萃取铜,研究了萃取时间、平衡水相pH、萃取剂N910的浓度、温度等因素对铜萃取率的影响,求得N910萃取铜的过程热效应ΔH=3.7 kJ/mol,提高硫酸浓度可提高铜的反萃取率.The extraction performance of copper（Ⅱ ） with tions was studied. The influence of equilibration time, eq Ng10 from ammoniacal/ammonium chloride soluuilibrium pH,extractant concentration, temperature on copper（ Ⅱ ） extraction was tested. The value of △H of the process was calculated to be 3.7 kJ/ mol. Copper（ Ⅱ ） stripping can be raised by raising H2SO4 concentration.
