建立了一种同时测定石灰石和白云石中镁、硅、铝、铁、锰、磷含量的电感耦合等离子体原子发射光谱法。试样以偏硼酸锂熔融，稀硝酸浸取，外标法定量。通过优化分析条件，得到镁、硅、铝、铁、锰、磷的检测限分别为0.071μg/mL、0.23μg/mL、0.23μg/mL、0.061μg/mL、0.0052μg/mL和0.015μg/mL。该法用于实际样品的测定，所得结果与标准样品的参考值相符，重复性与精密度良好，能够实现石灰石和白云石样品中多组分同时快速测定。

A method for the simultaneous determination of Mg, Si, Al, Fe, Mn and P in limestone and dolomite by inductively coupled plasma atomic emission spectrometry was established. The samples were melted by lithium metaborate, then extracted by nitric acid, quantified by external standard method. Under the optimal conditions, the detection limits of Mg, Si, Al, Fe, Mn and P were 0.071μg/mL, 0.23μg/mL, 0.23μg/mL, 0.061μg/mL, 0.0052μg/mL and 0.015μg/mL respectively. This method was employed in the determination of standard samples, the analytical results were accorded with the certified results, the repeatability precision is satisfactory. This method could be applied to the determination of multicomponent in limestone and dolomite simultaneously and rapidly.
