常规极谱测定微量和痕量元素主要是利用催化波和阳极溶脱技术。有关这方面的报道已见不少,这些方法灵敏度极高但是操作都较繁琐和严格,而且利用催化波难以一次连续测定多种元素。由于方波极谱,高频极谱和脉冲极谱的高灵敏度和高选择性使在无机微量和痕量分析中应用极谱法的可能性进一步扩大了。但是利用方波极
Conventional polarographic determination of trace and trace elements is the use of catalytic wave and anode stripping techniques. There have been many reports on this aspect. These methods are extremely sensitive but their operations are cumbersome and rigorous. Moreover, it is difficult to determine a variety of elements in a continuous manner by catalytic waves. Due to the high sensitivity and high selectivity of the square wave polarography, the high frequency polarography and the pulse polarography, the possibility of applying polarography in inorganic micro and trace analysis has been further expanded. But the use of square wave pole
