| 摘 要： | 建立了离子色谱测定氰化物分析方法,并确定了其优化条件.采用Metrosep A Supp 1作为氰化物分离柱,Metrosep RP作为保护柱,以0.1mol/L氢氧化钠和10%丙酮(V/V)组成淋洗液,淋洗液流速设置为1.0mL/min,选用工作电压80mV为最佳条件.实验证明该方法能在10min内完成氰化物的一次测定,氰化物浓度在1340μg/L~0.067μg/L范围内,线性关系良好(r大于0.9990),测定结果相对偏差小于10%.进样量为100μL时,氰化物检出限可以达到0.05μg/L.

| Abstract: | It has been finished for the analysis of cyanide by Ion Chromatography(IC),and the condition to determine cyanide by IC has been optimized too.The optimal condition was as follow: Metrosep A Supp 1 was selected as the separation column;Metrosep RP was selected as the guard column;A mixed solution of 0.1mol/L NaOH and 10%(V/V) Acetone was used as eluent with a flow rate of 1.0 mL/min,and working voltage was 80mV.The method could finish the determination of micro cyanide at one time.When the concentration of |
