Studies on the nicotine degradation in swimming pool water

The presented research assumes the implementation of experimental studies on the degradation, removal, and transformation of nicotine during processes that occur in swimming pool systems, including chlorination, UV radiation, and ozonation. Nicotine decomposition by-products during these processes have been also identified. The research has documented that nicotine in contact with sodium hypochlorite undergoes degradation that efficiency depends on the contact time, chlorine dose, and type of water matrix. The decrease of nicotine concentration over the time of UV radiation was observed. It achieved about 30% removal rate after 60 min. The effect of the type of aqueous matrix was not as significant in the case of UV irradiation and ozonation as in the chlorination process.
