印度详细地研究了用LIX87QN作萃取剂从含氨的碳酸铵溶液中萃取镍.氨溶液镍浓度为5.577kg/m~3,萃取相是用煤油稀释的10%(V)LIX87QN溶液,研究了pH(氨浓度)和碳酸铵浓度对萃镍的影响.当平衡pH由8.6升至10.0时,有机相中的镍浓度由4.43降至1.82kg/m~3.水相的碳酸铵浓度由45kg/m~3增至150kg/m~3时,有机相中的镍浓度由4.43kg/m~3降至3.55kg/m~3.发现由含60kg/m~3碳酸铵的水溶液在平衡pH为9.95时获得的有机相的
India has studied in detail the extraction of nickel from ammonia-containing ammonium carbonate solution using LIX87QN as extractant.The concentration of nickel in ammonia solution is 5.577kg / m ~ 3, the extraction phase is 10% (V) LIX87QN solution diluted with kerosene The effect of pH (ammonia concentration) and ammonium carbonate concentration on nickel extraction was studied.When the equilibrium pH was increased from 8.6 to 10.0, the concentration of nickel in the organic phase was reduced from 4.43 to 1.82 kg / m 3. The concentration of ammonium carbonate in the aqueous phase was changed from 45 kg / m ~ 3 to 150kg / m ~ 3, the concentration of nickel in the organic phase decreased from 4.43kg / m ~ 3 to 3.55kg / m ~ 3.It was found that when the aqueous solution containing 60kg / m ~ The organic phase obtained for 9.95 hours
