原子吸收光度法测定镉时铁的基体改进效应研究
MODIFYING EFFECT OF IRON BASE IN CADMIUN DETERMINATION BY ATONIC ABSORPTION SPECTROMETRY
【摘要】 用石墨炉原子吸收分光光度法测定环境废水中的痕量镉时，Mn、Cr、Ni、Cu、Co、Zn等共存元素干扰严重。用100mg／L的铁作为基体改进剂可消除上述共存元素的干扰，测定结果令人满意。
【Abstract】 When trace cadium is waste water is determinated by graphite furnance atomic absorption spetrometry, the coexisting ele-ments such as Mn, Cr, Ni, Cu, Co and Zn disturb significantly. The Disturbance can be eliminated when 1O0mg/l iron isused as basial modifier.
