Ex-Vivo Trace Assay Using Silver-doped Microfilm Electrode

Suw Young Ly and Juo Yang Kim

Trace lead is a dangerous environmental chemical that is associated with increased cancer risk. In this study, assay was conducted in ex-vivo mouse fluid, using a silver-doped microfilm electrode (SDE). The analytical working range was from 20 to 160 mg/L. Under optimum conditions, the micro range improved to 5-65μg/L while the detection limit was 5μg/L. Under a 10.0-mg/L Pb constant, the 10-time statistic was R 2 =9.795. This result was applied to mice ordure using SDE via cyclic and square-wave stripping voltammetry. As a result, 27.6μg/L Pd(II) was detected in the mice ordure solution with a precision value of ±12.5%. The techniques developed in this study using a probe that did not require pretreatment and expensive equipment can be applied in medical diagnosis.
