Reducing the pollution from the chemistry experiments is an important theme for protecting our environment and for education. We suggested some simple techniques to treat the pollutants from general chemistry experiments. The pollutants could be destroyed at relatively low cost and in some cases valuable products could be recovered. The following pollutants have been studied:( 1) organic solvents, such as cyclohexane and hexane, to be distilled and reused. (2) heavy metal ions , such as silver, copper, manganese and chromium (VI) ions to be converted into valuable laboratory chemicals . (3) triiodic ion, to be reduced to iodide ions using simple unit operation techniques.
