description This paper presents a portable phosphate detection system based on electrochemical reaction mechanism using cobalt modified microelectrodes. The microelectrodes were fabricated by MEMS (Micro-electromechanical Systems) technology and modified by electrodeposition of cobalt. The performances of the microsensors were characterized by testing a series of standard phosphate solution. MSP430F4793 microcontroller was applied to control the detection process at low power consumption. Comparing with the test results achieved by using traditional electrochemical workstation method, this portable detection system has similar characteristics with the concentration range from 10-6 to 10-4 mol/L.
