摘要
用HCl(1+3)浸取钼的氧化物,采取ICP—AES法测定,与经典硫氰酸盐光度法比较,结果一致;采用氢氧化钠加过氧化钠溶液熔融分离氧化物钼后的滤渣,硫氰酸盐光度法或ICP—AES法测定辉钼矿(硫化钼)。氧化铜量和硫化钼量之和与标准硫氰酸盐光度法测试的全钼量结果相吻合,并且通过测试样品中的全铁和氧化亚铁,所得铁的氧化情况与钼的氧化率结果相一致。
This paper is based on the achievements of previous studies,soaking molybdenum oxide with HCl（1＋3）,by ICP-AES method, compared with classical thiocyanate photometric method, the results are consistent. Using sodium hydroxide and sodium peroxide to melt the filtered slag after separating molybdenum oxide, thiocyanate photometry or ICP-AES method were used to determine molybdenite（molybdenum sulfide）. The sum of the two is consistent with the results of the total molybdenum content measured by standard thiocyanate photometric method. Through the test of total iron and ferrous oxide in the sample, the oxidation of iron is consistent with the oxidation ratio of molybdenum.
