| Abstract: | Determination of arenic in electronic-grade phosphoric acid by HG-AFS is researched. The instrument working conditions and the influences of KBH4 concentration, acidity, coexisting elements, phosphate matrix are studied. The detection limit of this method is 0.042 5 ng/mL with relative standard deviation of 1.66%. |
