现行高中生物(必修)教材第一册的学生实验“叶绿体中色素的提取和分离”的实验方法比较陈旧,步骤烦琐,实验耗时长,药剂材料用量多;实验步骤存在学生对滤液线画不匀、画不细,滤纸条在烧杯中不好固定,滤纸条上的滤液线与层析液接触过上或过下, The experimental method of the student’s experiment in the current high school biology (required) textbook 1 “Extracting and Separating Pigment from Chloroplasts” is obsolete, the procedure is cumbersome, the experiment takes a long time, the dosage of the pharmaceutical material is large, and the experiment step exists in the student’s drawing of the filtrate line. The unevenness and the painting are not fine, and the filter paper is not well fixed in the beaker. The filtrate line on the filter paper strip comes into contact with the chromatography solution, or it passes over it.
