本文在PH=7—8的硫酸根溶液中,以丹宁浸渍过的滤纸条,进行了钼的纸上斑点半定量测定的试验工作。在此条件下,W等廿几种常见元素均无干扰。但作为纸上斑点进行钼的半定量测定未见文献中有过报导。因此,它是测量微量钼的一个新方法。经实验证明,此方法简单,成本低,重现性好,灵敏度较高,所测得的结果与发射光谱法,比色法(硫氰酸盐-乙醚萃取法)比较均符合半定量误差的要求。它测定的范围是1.00—150ug/g.
In this paper, PH = 7-8 in the sulfate solution, with tannin impregnated filter paper, molybdenum paper semi-quantitative determination of the test work. Under these conditions, W and other twenty common elements have no interference. However, the semi-quantitative determination of molybdenum as a spot on paper has not been reported in the literature. Therefore, it is a new measure of trace molybdenum. The experiment proved that this method is simple, low cost, good reproducibility, high sensitivity, the measured results and emission spectrometry, colorimetry (thiocyanate - ether extraction) are in line with semi-quantitative error Claim. It measures the range of 1.00-150ug / g.
