黄铁矿、褐铁矿等单矿物中,常需测定铅、铜、镉、锌,镍、钴等元素。用原子吸收分光光度法虽可连续测,但由于被测元素含量低,需用较多试样,因而未能满足要求。极谱法的优点是几乎不消耗试液,便于连续测定。而脉冲极谱分辩率好,灵敏度高,对微量元崇的测定尤为有利。Abdull等人曾用脉冲极谱连续测定水中铜等六个元素,但仍需整合
Pyrite, limonite and other single minerals, often need to determine lead, copper, cadmium, zinc, nickel, cobalt and other elements. Although atomic absorption spectrophotometry can be measured continuously, but due to the low content of the elements to be tested, the need for more samples, which failed to meet the requirements. Polarography has the advantage of almost no consumption of test solution for continuous determination. The pulse polarographic resolution, high sensitivity, the determination of trace element Chong is particularly beneficial. Abdull et al. Have used pulsed polarography to continuously measure six elements of copper in water but still need to be integrated
