摘要
随着我国工业的高速发展,许多江河、湖泊受到了严重的污染,尤其是重金属污染对人体的伤害非常严重。研制的水质重金属检测系统是基于电化学阳极溶出伏安法对水样进行检测,采用无线通讯方式将数据传送至安卓终端进行分析计算,并且结合终端应用程序实现云存储和数据共享。与现有的水质重金属检测系统相比,该系统具有便携、试剂用量少、简单易用、成本低且能实现云存储和云共享功能等优点。将该系统用于铜离子的检测,在0～1 000μg/L浓度范围内,其具有较高的检测灵敏度(4. 064μA/(μg·L-1))和较高线性度(0. 985)。
With the rapid industrialization in China,many rivers and lakes are seriously polluted,especially by heavy metals,which are harmful to human health.The developed heavy metal detection system for water quality was based on electrochemical anode dissolution voltammetry to detect water samples,and adopted wireless communication to transmit data to android terminals for analysis and calculation.Cloud storage and data sharing were implemented in combination with terminal applications.Compared with the existing heavy metal detection systems,the proposed system has the advantages of portability,few reagent consumption,ease of use, low cost and capability of cloud storage and data sharing.Experimental results revealed that the proposed system has relatively good sensitivity (4.064 μA/(μg·L^-1 )) and relatively good linearity (0.985) to the cupric ion with the concentration ranging from 0 μg/L to 1000 μg/L.
