摘　　要： A novel chemiluminescence system for the determination of catechol in water was first described in this paper.It was based on the chemiluminescence reaction of catechol and hydroxyl radical that was the product of the reaction of Fe3+and H2O2.Rh6G could enhance the chemiluminescence intensity.The linear range was 10-2000μg/L with a detection limit of 5μg/L（3σ）.The relative standard deviation was 3.1% for 200μg/L of catechol（n=11）.The proposed method was successfully applied to the determination of catechol in water. A novel chemiluminescence system for the determination of catechol in water was first described in this paper. It was based on the chemiluminescence reaction of catechol and hydroxyl radical that was the product of the reaction of Fe^3 ＋ and H2O2. Rh6G could enhance the chemiluminescence intensity. The linear range was 10 -2000μg/L with a detection limit of 5μg/L（3σ）. The relative standard deviation was 3.1% for 200μg/L of eatechol（ n = 11 ）. The proposed method was successfully applied to the determination of catechol in water.
