【摘要】 <正> 用717氯型强硷性阴离子交换树脂和乙原磺酸钾一起加热,树脂吸附了磺原酸钾,树脂中含有二硫代羧酸基团,具有二硫代羧酸螯合树脂的一些特性。用静态法和柱法讨论了树脂对金属离子的吸附性能和解脱条件,共存离子对微量金属元素的干扰影响。用原子吸收法测定天然水中的微量铜、钴、镍、铅、镉、锰等元素,从回收率和精密度说明结果较满意。更多还原

【Abstract】 717 Cl—form resin and a pptassium xanthate heated together. The resin adsorpted potassium xanthate and contained dithiocarbamte alid radical, moreover, possessed some properties of dithiocarbamate alid chelate resin. Adsorption and desorption condition to metal ion and co-interference effect were studied. Determination of trace Cu,Co,Ni, Pb,Cd, Mn in natural water by atomic absorption spectrumetry explained satisfactory results. Recevery rate to determinate Cu, Co, Ni, Pb, Cd, Mn is: 97.6—102.4%, 99.5—100%, 96.4—100%, 99—100%, 99.9—101.7% and standard deviation is: 0.38 0.12 0.42 0.65 0.098 0.41.更多还原
