| Abstract: | A method of determing the Zn content in Dading ironstone by Atomic Abosorption Spectrophotometer was developed,in which the ironstone was dissolved in a mixed acid of HCl-HF-HNO3-HClO4,and the Zn content was determinded using the 213.9 nm peak of Zn.Being simple ,quick ,precise and accurate in operation , fitting the demand of producton and marketing with high precision. this method has yieded a recovery rate of 97%~101% with sample containing calibrating additions ,and in a relative standard deviations of 0.9%~1.2%. |
