钢中铅的测定,若采用化学法。化学光谱法,手续烦琐,需采用有机试剂富集,对人体有害。用经典极谱法测定,灵敏度不高,且在3M盐酸中,铅、锡二波重合。采用催化极谱法,能提高灵敏度,以示波极谱仪测量,方法简便,快捷,具有我国特色。但现有方法多用于矿石分析,对钢铁分析报道不多我们综合各方面文献资料经过分析比较,试验了盐酸—抗坏血酸—乙
Determination of lead in steel, if the chemical method. Chemical spectroscopy, cumbersome procedures, the need to use organic reagents enrichment, harmful to humans. Measured by classical polarography, the sensitivity is not high, and in 3M hydrochloric acid, lead, tin two waves overlap. The use of catalytic polarography, can increase the sensitivity to oscilloscope polarography measurement, the method is simple, fast, with our own characteristics. However, the existing methods are mostly used in ore analysis, and few reports on steel analysis. We comprehensively analyzed and compared various documents and tested the content of hydrochloric acid-ascorbic acid-B
