Abstract Artificial intelligence,especially machine learning,is opening up new possibilities for traditional chemistry experiments.Developing machine learning based research-type experiments is of great significance for cultivating students’ digital literacy and innovative capabilities.Herein,we report a digitized upgrade of a previous experiment on single metal ion detection.The modified experiment encompasses the simultaneous detection of Co2+ and Cu2+ ions via three-channel spectroscopic technique and the application of machine learning.Both random forest and multi-layer perceptron prediction models were established,which achieved efficient identification and accurate quantification of single and binary metal ions.Satisfactory results were achieved in real lake water analysis.The established research-type experiment not only provides a new approach for multicomponents analysis in complex samples,but also serves as a robust example for the digital-intelligent reform of experimental teaching.The experiment has been successfully implemented in teaching practice with positive educational outcomes.
