The analytical in vivo chromium ion was searched for using a voltammetric hollow-fiber dialysis sensor via square wave stripping voltammetry (SW) , cyclic voltammetry (CV) , and chronoamperometry. Under optimum parameters, the analytical results indicated linear working ranges of 50400 mg/l CV and 1080 μg/l SW within a 30-sec accumulation time. The analytical detection limit (S/N) was 6.0 μg/l. The developed method can be applied to in vivo tissues and in ex vivo toxicity assay, as well as to other materials that require chromium analysis.
采用方波 stripping 伏安法（SW）、循环伏安法（CV）和计时安培法，通过伏安式中空纤维透析传感器对体内分析铬离子进行了搜索。在最佳参数下，分析结果表明，在 30 秒的积累时间内，CV 的线性工作范围为 50400mg/L，SW 的线性工作范围为 1080μg/L。分析检测限（S/N）为 6.0μg/L。所开发的方法可应用于体内组织和体外毒性测定，以及其他需要铬分析的材料。
