돈을 번다는 것은 어려운 일이며 저축한다는 것은 더욱 어려운 일이고 더 나아가 돈을 아껴쓸 때와 푸짐하게 쓸 때를 가려낸다는 것도 매우 어려운 일이다. 이러한 일을 값있고 보람되게 처리하는 지혜를 가진 사람이 본받을만한 부자인 것이다.

In order to the study of oxidative degradation of nicotine by Ozonation, same factors which influenced nicotine decomposition by Ozone oxidation in various condition were investigated. The higher the pH of reacted solution, the longer the reaction time, the higher molecular polarization value of solvent, and temperature range -10℃∼10℃ of solution, the more nicotine was decomposition by Ozonation, it was the most decomposition rate of nicotine when the mole ratio of O3/nicotine was 2.5: 1 in methanol solution (about 100% reduction ratio of nicotine) and then the mole ratio of O3/nicotine was 1.3:1 in 0.05N-H2SO4 aqueous solution (about 60% reduction ratio of nicotine).
