给出了硝酸介质中 49 种阳离子和硫酸介质中 45 种阳离子的 BIO-RAD AG 50W-X8（100 至 200 目磺化聚苯乙烯树脂）的阳离子交换平衡分布系数。该系数是在阳离子总量与总树脂容量之比q=0.4时确定的，以确保与先前确定的盐酸系数的可比性。使用0.1N至4.ON的酸浓度。这些系数根据它们在 1N 酸中的值任意排列成选择性等级。包括多组分系统 V (V)-U (VI)-Sc (III)-Y (III) 的洗脱曲线； Na(l)-BeUl)-
Cation exchange equilibrium dis-tribution coefficients withBIO-RAD AG 50W-X8, 100-to 200-mesh, a sul-fonated polystyrene resin, are pre-sented for 49 cations in nitric acid and 45 cations in sulfuric acid media. The coefficients were determined at a total amount of cationto total resin capacity ratio q= 0.4, to ensure comparability with coefficients in hydrochloric acid determined previously. Acid concentrations from 0.1 N to 4. ON were used. The coefficients are arbitrarily arranged into selec-tivity scales according to their values in 1N acid. Included are elution curves for the multicomponent systems V (V)-U (VI)-Sc (lll)-Y (lll); Na (l)-BeUl)-
