| titleOfInvention | The detection method of antimony content in a kind of liquid form product |
| abstract | The present invention discloses the detection method of antimony content in a kind of liquid form product, comprises the following steps that order connects: the dissolving preparation of A, liquid sample: by liquid sample concentrated sulfuric acid dissolution; Being cooled to 35-45 DEG C, adding urea to producing without white smoke; Add thiocarbamide being not more than under the condition of 40 DEG C, the quality consumption of thiocarbamide be the 0.5-2 of liquid sample quality doubly; Thin up, amount of water is 100-500 times of liquid sample quality; Add the hydrochloric acid that mass concentration is 37%, boil and keep micro-2 ~ 3min that boils, being cooled to 65 ~ 75 DEG C, obtaining liquid to be measured; The calibrating of the middle antimony content of B, liquid sample: instill 0.1% methyl orange indicator by liquid to be measured, liquid to be measured being remained on 65 ~ 75 DEG C, to be titrated to pink color disappeared with potassium bromate standard solution be terminal.Inspection method of the present invention, does not need to drop into special analytical instrument, simple, quick, accurate, applied widely, selectivity is high. |
