中文摘要: 将流动注射化学分析仪引入水样中的氰化物测定。结果表明:其线性范围在 0~50 μg/L 时,均具有良好的线性 关系。氰化物方法的检出限为 0.2 μg/L。精密度 RSD 小于 3 %。氰化物的平均回收率为 95.8 %。
中文关键词: 流动注射  在线蒸馏  水样  总氰
Abstract:The determination of cyanide in water samples by continuous flow analyzer was introduced. The results showed that the linear range of the linear range of 0-50 μg/L. The detection limit was 0.2 μg/L. Precision RSD was less than 3 %. The average recovery was 95.8 %.
