泡沫浮选法在水质分析中的应用,国外已有许多报道。其中的共沉浮选法在国内已有报道,但离子浮选法国内未见报道。我们根据Fe~(2+)和二氮杂菲生成的配阳离子与阴离子表面活性剂形成离子缔合物而被浮选的特点,试用离子浮选-分光光度法测定水中痕量铁,获得了较好的结果。
Froth flotation method in the application of water quality analysis, there have been many reports abroad. Among them, the method of co-sinking and flotation has been reported in China, but no ion flotation has been reported in France. According to the characteristic of flotation of the complex cation and anionic surfactant formed by Fe 2+ and phenanthroline and the determination of trace amount of iron in water by ion flotation spectrophotometry, Better results.
