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.
