Abstract The digital experiment of handheld technology was introduced into the comprehensive chemistry experiment of Photo-Fenton synergistic degradation of organic pollutants,the experimental process video,images and digital information were obtained with wireless high-definition cameras,smart phones,Phyphox software and handheld redox potential sensors.The mathematical model of RGB value and organic matter concentration was established.This technology has the characteristics of on-site monitoring and detection,quantitative results,simple operation,high-throughput screening,less time-consuming,economical and portable.At the same time,the results show that obvious the color of the solution changes in macroscopic are shown in the images,in which the redox potential data changes and photodegradation curve are detected in microcosmic by the help of sensor equipment.The combination of macroscopic phenomena and microscopic characterization visually presents the existence of the Photo-Fenton synergistic reaction process and the catalyst participating in the reaction process.The digital level of teachers is improved by these strategies,and the application of hand-held technology digitization in experiment are helpful not only in arousing the students' interest but also in developing the students' scientific thinking and innovative consciousness.
