| titleOfInvention | Quantitative analysis method for chromium in steel |
| abstract | (57) [Abstract] [Purpose] To provide an ICP method for quantifying chromium in the above-mentioned steel with high sensitivity in order to quantitatively grasp the relationship between the compounding composition and the properties of the Ni-Cr-Mo-V steel. The purpose is to [Structure] Chip-shaped steel is degreased and dried, aqua regia is added to decompose it with heat, then cooled, and the filtrate obtained by filtering this decomposed solution and the filter paper are ashed to give sodium peroxide: carbonic acid. After melting with a flux of soda, heating and dissolving by adding hydrochloric acid, a mixed solution with a filtered filtrate is prepared, and strontium is added to this mixed solution as a standard substance, and then a fixed amount is added with ion-exchanged water, Provided is a method for quantitatively analyzing chromium in which chromium is quantified by an internal standard method by measuring the emission intensity of chromium by using this as a sample solution and using a high frequency inductively coupled plasma emission method. |
