【摘要】 采用慢扫速示波计时电位法同时测定铝合金中的铅与锌。该方法具有简便、快速,干扰小,选择性高等优点,特别适合于在其它离子共存条件下,测定合金样品中某种金属元素的含量。通过对铝合金样品中铅、锌测定,平均回收率和RSD分别为9918%,9900%和11%,16%。更多还原

【Abstract】 In this paper, by means of slow sweep oscillographic chronopotentiometry, lead and zinc were determined. The method has many advantages. It’s apparatus is simple, operating is fast, the selectivity and sensitivity is high. The proposed method has been applied directly to determine lead and zinc in aluminium alloy, the average recovery and RSD were 99 18%, 99 00% and 1 1%, 1 6%, respectively.更多还原
