铅铝合金成份简单加进锶的含量将影响合金的性能,是必检的元素。应用容量法测定锶其分析手续繁杂,时间较长。我们采用了原子吸收分光光度法测定铅铝合金中的锶,用钙盐作抑制剂,并消除铝的干扰,其方法简便,缩短了分析时间。该法仅适用于铅铝合金锶的分析。 一、仪器及试剂 1.仪器 原子吸收分光光度仪:WFX—1 B型
Simple addition of lead aluminum alloy composition will affect the performance of the alloy strontium content is bound to seized elements. Determination of strontium using the volumetric method of analysis of complicated procedures, a long time. We used atomic absorption spectrophotometry for the determination of strontium in lead-aluminum alloys, using calcium salts as inhibitors and eliminating the interference of aluminum. The method was simple and shortened the analysis time. This method is only applicable to the analysis of lead-aluminum alloy strontium. First, instruments and reagents 1 instrument atomic absorption spectrophotometer: WFX-1 B type
