The design of automatic detection system for microscale arsenic and fluoride ions in drinking water has been studied. The overall technical route of the system, automatic liquid sampling, acquisition circuit, control software and signal processing are mainly introduced. For the data collected, the signal de-noising algorithm and peak area calculation method based on wavelet analysis are provided in the system, to make the calculation of metal ion concentration fast and accurate. The whole test system features simple operation, user-friendly man machine interface, and supporting detection parameter setup; in addition, the system can be unattended operated or implemented via remote wireless control, thus the real time rapid on-site monitoring for the microscale harmful arsenic and fluoride ions in drinking water becomes feasible.
