| titleOfInvention | A kind of ICP determination method of manganese, phosphorus, chromium and aluminum components in micro-nitrogen alloy |
| abstract | The invention provides a method for ICP determination of manganese, phosphorus, chromium and aluminum components in micro-nitrogen alloys, which relates to the technical field of component determination and includes the following steps: S1: weighing micro-nitrogen alloys, sieving and drying, and then cooling to room temperature, Obtain the sample; S2: weigh the sample and place it in a polytetrafluoroethylene beaker, add nitric acid and heat, and add hydrofluoric acid dropwise while shaking until the sample is completely dissolved; S3: add perchloric acid to the beaker and heat Concentrate and then remove and cool; the present invention pre-treats the micro-nitrogen alloy sample, completely opens the sample, obtains the sample to be tested, and meets the requirements of ICP detection. When the sample is dissolved, it is processed in the same way to obtain the standard solution , the standard solution and the sample are carried out synchronously, and the accuracy of the detection curve is ensured by comparing the measured value of the standard solution with the existing certified value, so as to detect the product to be tested, to ensure the accuracy of the detection, and to prepare the test sample at one time. The test product does not need separate pretreatment for each element, which improves the detection efficiency. |
