基于微流控纸基装置快速检测5种金属离子
A microfluidic paper-based device for rapid detection of five metal ions
摘要
Abstract
[Objective]To design a microfluidic paper-based device and explore its qualitative detection capabilities for mercury,lead,aluminum,iron,and copper ions,as well as its detection capabilities in actual samples.[Methods]This study constructs a microfluidic paper-based device by combining five complexing reagents[ammonium aurintricarboxylate(ATA),dithizone(DZ),diphenylcarbazide(DPC),sodium diethyldithiocarbamate(DDTC),and eriochrome black T(EBT)]with masking agents.The reaction is tracked based on the Euclidean distance(ED)before and after the reaction.[Results]The target metal ions can cause obvious color changes in the paper-based device within a rapid response time of 10 s.Even in the presence of other common metal ions,this device still shows good selectivity.The paper-based device has the ability to detect in actual samples such as tap water,tea,and juice.[Conclusion]This device is characterized by simple preparation,portability,and a fast response.It can be used for qualitative detection of mercury,lead,aluminum,iron,and copper ions.关键词
