报道了CL N1 92 3萃淋树脂对钨和磷的吸萃性能 ,研究了该树脂对高量钨溶液中微量磷的色谱分离条件。通过动、静态法试验结果表明 ,CL N1 92 3萃淋树脂在pH =7.80～ 8.32的弱碱性NaHCO3溶液中对粗Na2 WO4溶液中微量杂质磷具有很强的吸萃能力 ,动态吸萃率达 90 %以上 ,βP/WO3达 1 0 0左右 ,高纯钨的直收率约 80 % ,分离后钨溶液中磷的含量由 0 0 50～ 0 50g/L降至 0 0 1 5g/L以下 ,磷的去除率达 70 %～ 97%。 The extraction performance of CL N1 92 3 extraction resin for tungsten and phosphorus was reported. The conditions for the chromatographic separation of trace phosphorus in high tungsten solution were studied. The results of dynamic and static tests show that the CL N1 92 3 extraction resin has a strong ability of absorbing phosphorus in the dilute alkaline solution of NaHCO3 at pH = 7.80 ~ 8.32. The dynamic extraction efficiency Up to 90%, the ratio of βP / WO3 is about 100, and the direct yield of high purity tungsten is about 80%. The content of phosphorus in the tungsten solution after separation is reduced from 0 0 50 ~ 0 50g / L to 0 0 15g / L The phosphorus removal rate is 70% ~ 97%.
