| titleOfInvention | A method for quantitative analysis and detection of arsenic, antimony and bismuth in geological samples |
| abstract | The invention discloses a quantitative analysis and detection method for arsenic, antimony and bismuth in geological samples, which specifically includes the following steps: adding newly prepared aqua regia with a volume ratio of HCl:HNO 3 to 3:1 into the sample to be tested, and dissolving in a water bath , shake well, deionized water to constant volume, add thiourea-ascorbic acid and carry out thiourea reaction to obtain a sample treatment solution; take potassium borohydride and potassium hydroxide in a beaker, mix absolute ethanol and 0 ℃ ice water in proportion Add the beaker to obtain the potassium borohydride treatment solution; add the sample treatment solution and the potassium borohydride treatment solution to the atomic fluorescence spectrometer and measure the fluorescence intensity to obtain the arsenic, antimony and bismuth content in the geological sample. The invention can control the slope of the linear equation of hydride generation-atomic fluorescence spectrometry to measure arsenic, antimony and bismuth by changing the mixing ratio of 0°C ice water and anhydrous ethanol, so as to widen the analysis and detection range, and control the temperature at 0°C to reduce the amount of boron The decomposition rate of potassium hydride can prolong the analysis time and improve the temperature of detection. When the mixing ratio is 1:1, the upper limit of detection is increased by 1 to 2 orders of magnitude. |
