摘要
研制了基于电化学法的便携式过氧化氢浓度检测仪,可用于食品过氧化氢(双氧水)残留检测。过氧化氢与测试条上的专用试剂反应后,会产生微弱电流信号,通过检测此反应电流来确定过氧化氢的浓度。介绍了该仪器的软件设计和硬件选型。测试结果表明,仪器的测试误差较小并有较高的分辨率。
A portable concentration detector of hydrogen peroxide based on electrochemistry was developed.It is used to detect the existence of hydrogen peroxide in foods.After the reaction between hydrogen peroxide and the specific reagent on a disposable test strip,a micro-current signal is generated. The concentration of hydrogen peroxide in the sample will be quantitatively determined by the generated current signal.Both hardware and software design of the meter are presented.Testing experiments were carried out to access the accuracy and resolution of the meter.
