摘　　要：本文叙述了含砷铝标准物质的制备过程和定值结果。采用了间接加入法，以异基体的Ｃｕ－Ａｓ中间合金形态把Ａｓ加入并均匀分布在铝液中。用制备出的标准物质制作校准曲线，进行光谱分析，其结果与仲裁结果相符。本标准物质与俄罗斯的同类标准物质比对实验表明：本标准物质的主要特性指标达到或超过俄罗斯的水平。本标准物质制备成功，填补了国内无含Ａｓ铝标准物质的空白，本标准物质可替代同类进口标准物质。The preparation procedure and evaluation result of aluminum reference material containing arsenic are described. Element As is added indirectly and distributed uniformly in aluminum melt in the form of variant base metal of Cu As intermediate alloy.A working curve was made from the prepared reference material and analyzed by means of spec2trum with the result identical to that of arbitration.A comparative test between this material and Russian equivalent shows that main features of this material are identical to or even better than those of Russian′s.The successful preparation of this material has filled the gap that there was no aluminum reference material containing arsenic before in China this material is able to take the place of imported one.
