本文以铜离子选择电极作指示电极,饱和甘汞电极作参比电极,在同一酸度下,采用 Trien和 EDTA 两种滴定剂,同时连续滴定铜(Ⅱ)、锌(Ⅱ)两离子,结果满意,用于人发中微量铜(Ⅱ)、锌(Ⅱ)离子的测定,其标准偏差为±2.6μg,方法回收率为97.7～104%之间,结果与原子吸收光谱法基本一致。 In this paper, copper ion-selective electrode was used as the indicator electrode and saturated calomel electrode as the reference electrode. Under the same acidity, Trien and EDTA were used as titration electrodes and titration of copper (Ⅱ) and zinc (Ⅱ) The method was applied to the determination of trace amounts of copper (Ⅱ) and zinc (Ⅱ) in human hair. The standard deviation was ± 2.6μg, and the recovery rate was 97.7% ~ 104%. The results were in good agreement with atomic absorption spectrometry.
