近年来,由于砷化物的致癌作用,引起人们的注意,因此砷化物在采矿、冶炼和使用等过程中对环境的污染问题,已成为劳动保护的重要问题之一。为了调查砷化物对环境污染的情况,需要有一个灵敏、简便、可靠的测定方法。古典的古蔡氏班点比色法,虽然灵敏,但重现性差,适宜用在半定量分析。钼兰比色法灵敏,但不是砷的特异
In recent years, due to the carcinogenic effect of arsenic, aroused people’s attention, so the arsenide pollution in the process of mining, smelting and use, has become an important issue of labor protection. In order to investigate the environmental pollution of arsenic, a sensitive, simple and reliable method of determination is required. Classical ancient Chua class point colorimetry, although sensitive, but poor reproducibility, suitable for use in semi-quantitative analysis. Molybdenum colorimetric sensitive, but not specific to arsenic
