| 摘 要： | 以基体匹配的混合标准溶液为外标校正溶液, 采用115In - 10 3 Rh双内标校正系统, 通过单个元素Ca, Cr, Ti, Ba, La, Ce, Pr的氧化物、氢氧化物产率的测定, 计算其等效干扰离子浓度, 并进行校正, 从而有效地抑制了分析信号的漂移、基体效应及多原子离子干扰.针对不同岩性的地质样品, 分别采用酸消解、碱熔融样品制备体系, 在POEMSⅢ上建立了等离子体质谱法同时测定微量、痕量、超痕量元素的分析方法.用于国际地质标样AGV - 1 (安山岩), BH VO - 2 (玄武岩), GSR - 3 (玄武岩), DNC - 1 (橄榄岩), RGM - 1 (流纹岩), G - 2 (花岗岩), JG- 2 (花岗岩) 的分析, 结果令人满意.

| Abstract: | The analytical method of major, trace and ultra_trace elements is applied to geological samples using ICP_MS. In order to minimize matrix effects of inter_elements, the matrix_matched calibration solutions were prepared, simulating the composition of natural rocks obtained from statistically_calculated average values of 20 geological samples. The resulting values are then normalized. Two separate internal standards of 115 In_ 103 Rh are selected to compensate the drift of analytical signals. Polyatomic ion interference is calibrated by measuring the oxides (MO +) and hydroxides (MOH +) with individual element solution for the ratio of MO +/M + and MOH +/M + and the concentrations are then equivalently calculated. The proposed method is applied to the analysis of seven standard reference materials. For the most trace elements, the relative errors between this work and the recommend values are greater than 10% and the relative standard deviations are greater than 5%. |
