%X A method for the determination of seawater chemical oxygen demand (COD), using oven instead of electric furnace to heat samples, was proposed. In this study, standard samples were heated under different conditions of temperature and time to obtain optimum heating conditions. The concentration range of the method was then assessed under the optimum operation conditions. In the end the method was applied to analyze seawater samples in comparison with the electric furnace method. All these results showed a good accuracy and precision of the oven heating method with less time and energy consumed, expecially when a large number of samples were analyzed simultaneously.
