| Abstract: | By using the scientific and technological innovation project for university students,a fan-like microfluidic chip is designed and fabricated.The determination of trace Cr^3+in water by microfluidic injection chemiluminescence system is realized by catalyzing the chemiluminescence reaction of luminol-hydrogen peroxide with Cr^3+under alkaline conditions.The experiment shows that the method has wide linear range,good precision and high sensitivity,which has greatly trained the students’ability of scientific and technological innovation. |
