全苏标准提出的硫氰酸盐测钼法,灵敏度和选择性不高、重现性差而且要取大量水样。由于饮用水中钼含量低,通常在测定前要预浓缩。为了克服这些缺点,作者提出了不同预分离干扰组分直接测定饮用水中钼的方法。 Thulium cyanide standard molybdenum method proposed by the whole Soviet Union, sensitivity and selectivity is not high, poor reproducibility and to take a large amount of water samples. Due to the low content of molybdenum in drinking water, preconcentration is usually performed before the measurement. In order to overcome these shortcomings, the authors propose a method for direct determination of molybdenum in drinking water by different pre-separation interference components.
