摘　　要：应用电感耦合等离子体原子发射光谱（ICP—AES）法，对硼硅酸盐玻璃中的常量元素Si、Ca、Al、B及微量元素Fe、Ti、Mg进行测定。在优化的工作条件下，各元素的检出限：SiO2 0．026μg／mL，Ca0.0002μg／mL，A10．028μg／mL，B0.005μg／mL，Mg0.0002μg／mL，Fe0．006μg／mL，Ti0．005μg／mL。样品测定结果的相对标准偏差（n=6）在0．02％～1．47％之间，加入标准溶液的回收率为93．0％～103．2％。采用该方法对硼硅酸盐玻璃标准样品进行测定，测定值与标准值一致。A method for the determination microelements of Si, Ca, Al, B and macroelements Fe, Ti and Mg in borosilicate glass by inductively coupled plasma atomic emission spectrometry （ICP - AES）was described. After operation parameters of apparatus were optimized, the detection limits of the method were 0.026 μg/mL for SiO2 ,0.0002 μg/mL for Ca,0.028 μg/mL for Al,0.005 μg/mL for B,0.0002 μg/mL for Mg,0.00 6μg/mL for Fe,0.005 μg/mL for Ti. The relative standard deviation of this method was between 0.02% -1.47% （n = 6） , and the standard addition recoveries were in the range of 93.0% -103.2%. The method was used to determine the amount of elements in the borosilieate glass standard reference material with satisfactory results.
