建立了一种阳极溶出伏安法快速测定谷物中的镉含量。样品经微波消解后,采用玻碳电极为工作电极,Ag/Ag Cl电极为参比电极,铂电极为对电极,测定谷物中镉含量,其检出限为0.4μg/L。采用标准加入法,平均回收率100%~104%;某一浓度样品同时测定6次,其变异系数2.43%。该方法稳定、快速和准确,可广泛用于粮食的安全事件应急监测。 Anodic stripping voltammetry was developed for the rapid determination of cadmium in grain. After the samples were digested by microwave, the detection limit was 0.4μg / L with the glassy carbon electrode as the working electrode, the Ag / AgCl electrode as the reference electrode and the platinum electrode as the counter electrode. The standard addition method, the average recovery of 100% to 104%; a concentration of 6 samples at the same time, the coefficient of variation 2.43%. The method is stable, fast and accurate and can be widely used in the emergency monitoring of food safety incidents.
