| titleOfInvention | A kind of detection method of niobium and tantalum |
| abstract | The invention provides a detection method for niobium and tantalum, belonging to the field of element content detection. The sample to be tested is mixed with acid and then digested to obtain a digested solid; the digested solid is mixed with an extraction medium for redissolving to obtain a liquid to be tested; the extraction medium includes one of inorganic strong acid, tartaric acid and hydrofluoric acid. One or more, the inorganic strong acid is nitric acid or aqua regia; the liquid to be tested is detected by inductively coupled plasma mass spectrometry to obtain the content of niobium and tantalum. In consideration of the degree of digestion of the sample to be tested and the hydrolysis of niobium and tantalum in the digested solids during redissolving, the invention improves the conventional open dissolving method of hydrofluoric acid, nitric acid and perchloric acid, and adopts strong inorganic acid, tartaric acid and hydrofluoric acid. One or more of the acids are the extraction medium, and tartaric acid and hydrofluoric acid are introduced to inhibit the hydrolysis of niobium and tantalum in dilute acid solution. Combined with inductively coupled plasma mass spectrometry (ICP-MS), the detection is improved. The accuracy of niobium and tantalum. |
