摘要：

采用干灰化法-硝酸溶液溶解样品,分光光度法测定面制食品中铝。结果表明,溶液酸度控制在0.2%为最佳,最佳测定时间以20 min为宜,该法精密度RSD%在7.0~8.5之间,添加回收率在92.5%~99.2%之间,与国标比色法比较,结果无显著差异,其中精密度还优于国标比色法。该法完全可以作为目前国标比色方法的补充,适于批量样品测定,前处理液可用于其它金属元素联测,对实现低碳绿色分析具有现实意义。

摘要：

Samples were dissolved by nitric acid after ashing,and aluminum was tested by spectrophotometry,the results showed that the best acidity of nitric acid was 0.2 %,the best measured time was 20 min,the precision RSD % was between 7.0 %-8.5 %,and the recoveries were between 92.5 %-99.2 %.Compared with the GB code color method,the result had no remarkable difference,in which accuracy also surpassed the GB code color method.The method could be as a supplementary method for current national standard,and suited for the determination of bulk samples,the pre-treatment solution could be used as other metallic elements associated measurements.
