摘要
在大学分析化学实验课程中引入微流控芯片和智能手机的相关内容,不仅可以提高学生的学习兴趣和动手能力,而且能够彰显课程的发展性与时代性.磷钼蓝比色法是分析化学实验教材中磷含量测定的常用方法,利用微流控芯片的集成优势和智能手机的拍照和图片分析功能,可以有效减小试剂用量,避免显色时间不同导致的误差,显著提高分析效率.
The introduction of microfluidic chips and smartphones into analytical chemistry experimental courses can not only improve students’interest in learning and practical ability,but highlight the development and epochal character of the course.Phosphorus molybdenum blue colorimetric method is a common method to determine the content of phosphorus in analytical chemistry experiment textbook.By means of the integration of microfluidic chip and the camera and image analysis application in smartphones,the reagent of dosage is effectively reduced,the error caused by the difference of color development time is avoided,and the efficiency is improved significantly.
