矿石中微量钼的催化极谱测定已作为一个成熟的方法被广泛地采用。高含量钼的极谱测定近年来在国内外已有报导,由于波形不够理想,再加上某些元素的干扰没有找到一个合适的解决办法,因此在实际应用上仍有一定的困难。 矿石中常量钼的测定通常采用硫氰酸盐比色法,由于该方法的测定范围较窄,对于同一批样品中个别高量钼的测定,又必须采用其他方法测定,给分析者带来极大的不便。
Catalytic polarographic determination of trace molybdenum in ore has been widely adopted as a mature method. In recent years, polarographic determination of high content of molybdenum has been reported at home and abroad. Due to the unsatisfactory waveform and the interference of some elements, a suitable solution is not found. Therefore, there are still some difficulties in practical application. Determination of the constant molybdenum ore usually thiocyanate colorimetric method, due to the narrow measurement range of the method, the same batch of samples for the determination of a certain amount of high molybdenum, but also have to use other methods to measure, to bring the analyst pole Big inconvenience
