应用火焰原子吸收光谱法测定了金属纽扣中镍的释放量。样品用旋转磨损试验机进行磨损实验,然后用人工汗液进行浸泡。前处理以后,取处理溶液进行火焰原子吸收光谱法分析,标准曲线用镍元素的标准溶液制作。在此基础上用标准加入法作了回收实验,测得镍元素的回收率在95.0%~106.5%之间。 The release of nickel from metal buttons was measured by flame atomic absorption spectrometry. Samples were subjected to a wear test with a rotary wear tester and then soaked with artificial sweat. After the pretreatment, the treatment solution was subjected to flame atomic absorption spectrometry analysis, and the standard curve was prepared using a standard solution of nickel element. On this basis, the standard addition method was used to make the recovery experiment. The recovery of nickel element was between 95.0% and 106.5%.
