离子交换树脂分配系数
ion exchange resin distribution coefficient
1 121』iaohuan shuzhj fenPei xishu离子交换树脂分配系数(ion exehange resindistribution eoeffieient)离子文换达到平衡时,被交换离子A、B在离子交换树脂相和溶液相中浓度比的比值。又称选择系数,用Kd表示: ,_鱼纽立鱼胆~ 凡一右万荃葬落蔽式中M.、Ml分别为离子交换树脂相和溶液相中被交换离子的摩尔分数。分配系数与离子交换树脂的离子形式、类型、交联情况和溶液中溶质的种类、浓度以及存在于同一溶液中的其他溶质有关。在低的溶质浓度时,分配系数与溶质浓度无关。 分配系数是反应交换平衡的一个重要参数。根据两种离子分配系数的比值,可判断交换分离的难易程度。比值为1,表明离子交换树脂对两种离子无选择性;当大于1或小于1时,则表明离子交换树脂对某种离子具有选择性。例如在分离相邻稀土元素时,一般要求此比值在1.2或更大。 (刘惠卿马荣驻)
