本文报导了P507-萃淋树脂的合成方法。测定了稀土元素在P507树脂与盐酸溶液间的静态分配系数。并且讨论了盐酸浓度、温度、聚合物中P507的浓度及氯化铵量对静态分配系数的影响。
This paper reports the synthesis of P507-extraction resin. The static partition coefficients of rare earth elements between P507 resin and hydrochloric acid solution were determined. The effects of hydrochloric acid concentration, temperature, concentration of P507 in the polymer and the amount of ammonium chloride on the static partition coefficient were also discussed.
