原子吸收分光光度法测定三氯异氰尿酸中的钠

摘要

It was introduced cross-linked with different cyanuric acid in sodium by atomic absorption spectrum analysis method.Sample was determine by atomic absorption spectrometry after pretreatment.The result showed that sodium linear in the range of 0.0 μg/mL ～ 5 μg/mL,the linear correlation coefficient was 0.999 8,the detection limit of 0.005 μg/mL,adding in the 0.005％,0.01％,0.02％,three levels of the average recovery was 90％ ～100％,relative standard deviation was less than 1.7％ (n =6).Experiment was proved that the method can completely meet the need of the factory control monitoring.%建立了三氯异氰尿酸中钠的原子吸收光谱分析方法.试样经预处理后,采用原子吸收光谱法进行测定.结果表明,钠的线性范围为0.0 μg/mL～5μg/mL,线性相关系数为0.999 8,检出限为0.005 μg/mL,在0.005％、0.01％、0.02％三个添加水平的平均回收率为90％ ～ 100％,相对标准偏差小于1.7％(n=6).试验证明该方法完全能够满足公司中控监测的需要.
