摘　　要：引导学生自制花青素提取液进行特征检测、含量计算,并使其与5种金属离子进行络合反应可行性测试,筛选出现象明显的络合反应进行分析比较。利用数码成像比色法分析溶液浓度与色度的关系,构建该络合物的外部校准曲线。该实验将定性观察与定量分析相结合,通过将络合反应可视化表述,进一步提高学生对化学实验的兴趣,实现学生高层次认知思维的进阶,更好地投身于科研创造之中。During the experimental process,students are guided to prepare anthocyanin extract solution for characteristic detection and content calculation,and to conduct feasibility tests with five different metal ions to screen for obvious complexation reactions for comparative analysis.By using digital imaging colorimetry to analyze the changes in solution concentration and color,an external calibration curve for the complex is constructed.This experiment combines qualitative observation with quantitative analysis,further enhancing students'interests in chemical experiments by visualizing the complexation reaction,advancing their high-level cognitive thinking,and better engaging them in scientific research and innovation.
