Abstract

SODIUM CHLORATE is one of the most important chemical components which is produced via ELECTROLYSIS process. Electrical power consumption and economic of the process are directly related to the design of ELECTROLYSIS cell, material of construction and structure of the electrodes. In this research the optimum conditions for the production of SODIUM CHLORATE in a lab scale ELECTROLYSIS cell incorporating DSA electrodes was investigated. Experiments were conducted in order to elucidate the effect of process variables including current density, temperature, and time, on the voltage of the cell and the amount of the product. The feed was 1000 mL aqueous solution containing 300 g/L NaCl, as its initial concentration, and the anode was one of DSA with an effective surface area of 10 cm2. The TAGUCHI method was used to design the strategy of the experiments. The results revealed that at the operating conditions of T=85°C, pH=6.8-7, I=4 A, and an operation duration of 2.5 hr, an amount of 163.86 grams of ClO3- was produced while the energy consumption was equal to 7221.84 kWhr/ton ClO3-. Meanwhile, the voltage of the cell was 3.3 V which was increased about 0.2-0.3 V during the 2.5 hr of operation.
