Abstract: According to some research achievements, an innovative exploratory teaching experiment—Determination of copper(II) in multiple trace elements injection II by chemical sensor, was explored and designed. This experiment is stable, repetitve, simple to operate, and covers many knowledge points and research topics for students to explore by themselves. Compared with the fundamental experiments in organic chemistry course, this experiment involves multiple disciplines, which is strong professional and interesting for pharmacy students. It is found that these measures can improve the teaching quality, and develop the students innovation ability, scientific literacy and research ability.
