A voltammetric electronic tongue with automated operation based on the flow injection (FIA) technique was applied to the characterization
of wastewaters coming from the paper mill industry. A metallic multielectrode array – formed by platinum, gold and rhodium electrodes – was
employed as the detection system, while the measurements were based on large amplitude pulse voltammetry (LAPV). LAPV consisted in scans
of pulses from to 0 to 1.8V at 0.2V steps. Five current values were recorded for each pulse, so a set of 300 current values (three electrodes×20
pulses×five values) was recorded for each sample. Samples were first discriminated using Principal Component Analysis (PCA), while Artificial
Neural Networks were used for the characterization and prediction of chemical oxygen demand, conductivity and pH. The system may be used for
the quick identification and monitoring of the quality of used waters in these industrial facilities.
英语在考完四级就荒废掉了,现在要做毕业论文,第一段就卡牢了,请各位大大侠帮个忙,非常感激!当然积分也不会少滴.谢谢拉啊!
參考答案:回家看看再回复你.....
根据流量的喷射技术(FIA)制造的带有自动操作语音功能的电子伏安表被用于对造纸厂排放废水特性分析.
一支金属的多用电极由白金/黄金和铑电极组成,并被用作检测系统,这种测量是运用高振幅脉冲伏安法(LAPV)
LAPV保存扫描从0-1.8V之间每0.2V一个刻度的脉冲.
每个脉冲记录5个电流值,每个例子记录一组300个电流值(3电级X20脉冲X5个电流值).
运用主要元件分析仪(PCA)对各个例子先行区分,而人造神经系统网络用于特性分析和氧需求量/导电性和PH值的预报.
这套系统可用于此类工业安全排放水质量的快速鉴定和监控.
以上答案供参考.应该问题不大.
