abstract
The compound, 5-chloro-2-(2,4-dichlorophenoxy)phenol, also commonly known as Triclosan, is added as an antibacterial agent to many personal hygiene and household cleaning products. However, previous research has shown that Triclosan reacts readily with the chlorine typically found in household tap water and pool water. Previous research has also indicated that not only does the reaction with chlorine reduce the efficacy of the antibacterial function of Triclosan, but also produces carcinogenic compounds, including chloroform and 2,4,6-trichlorophenol. The main purpose of our research was to study the kinetics of the Triclosan/chlorine reaction and determine the rate law. The kinetics were studied using a DPD colorimetric method and reactions were performed at ambient room temperature and in a pH range of 6-7. The rate law was determined to be Rate = k[Cl2][Triclosan]3/2, which indicates a first-order dependence on the chlorine concentration and three-halves order dependence on the Triclosan concentration. Our research also indicated that for a one-to-one concentration ratio of Triclosan and chlorine, the chlorine was completely used up in less than thirty minutes of reaction time, thereby indicating a decrease in the effectiveness of the antimicrobial capabilities of both the chlorine and the Triclosan. note
