美国地质调查所Sue Miller博士最近在TGCP—Project156-Phosphorites的《Newsletter》,No12(1983)上,提出一种盐酸-钼酸铵试磷方法,其试验步骤如下: 1.先在被测试的岩石或标本上,滴加几滴浓度为10％的盐酸。 2.在已滴加的盐酸中放上几粒(小于小米粒大小的颗粒2—3颗即可)白色的钼酸铵晶粒。
Dr. Sue Miller of the United States Geological Survey recently proposed a method for the determination of phosphorus by ammonium molybdate hydrochloride in the Newsletter No. 12 (1983) of the TGCP-Project 156-Phosphorites. The test procedure is as follows: 1. The rock to be tested Or specimens, a few drops of a few drops of hydrochloric acid concentration of 10%. 2. Put a few drops in the hydrochloric acid has been added (less than the size of 2-3 grains of rice particles can be) white ammonium molybdate grains.
