Zusammenfassung: | The invention relates to a method for rapidly determining the content of tungsten and molybdenum in a geological sample, and belongs to the technical field of tungsten and molybdenum detection.The method comprises the specific treatment steps that the geological sample to be detected is weighed, the geological sample added with an alkali melting agent is put into a platinum crucible, and then the platinum crucible is put into a muffle furnace to be subjected to melting treatment; extracting the molten sample with water, heating to dissolve frits, and fixing the volume; separating the solution, adding a tetraphenylboronic acid solution, and centrifuging to obtain supernate as to-be-detected clear liquid; and directly measuring the tungsten and molybdenum concentrations of the clear liquid to be measured by using an inductively coupled plasma emission spectrum or an inductively coupled plasma mass spectrum, and calculating the tungsten and molybdenum contents in the geological sample. According to the method, t |
