摘　　要：采用偏硼酸锂熔样 ,电感耦合等离子体原子发射光谱 (ICPˉAES)法对粉煤灰实现一次熔样 ,全组分同时分析。对影响光谱测量的各种因素进行了较详细的研究 ,确定了最佳测定条件。该法的检出限为 0 .0 0 9～ 0 .83 1μg·ml-1,回收率为 91.5 4%～ 10 4.45 % ,RSD <3 .2 2 %。方法准确、快速、简便 ,用于粉煤灰中全组分测定 ,结果满意。It is reported in theis paper that the lithium metaborate fusion method decompose technique is used in the Inductively Coupled Plasma Atomic Emission Spectrometry(ICPˉAES)method determination of all components of fly ash. The various factors affectig spectrum intensity were examined in details. The optimum conditions for the determination if tested and discussed. The limit of the method is 0.009～0.831μm·ml -1 .The recycling rate ranks from 91.54% to 104.45%. RSD is less than 3.22%. This method is accurate, quick acquired and convenient. It is used in the determination of all components of fly ash with the result is satisfactory.
