This study surveys the possibility to optimally produce active chlorine from synthetic saline solutions using electrolysis by Response Surface Methodology (RSM). Various operating parameters, such as sodium chloride concentration, electrical potential and electrolysis time were evaluated. Central composite design (CCD) was applied to determine the optimal experimental factors for chlorine production. The experimental design, statistical analysis of the data and optimization were performed using R 3.5.3 software. The results showed that the optimum value of electrical efficiency (42 mg Cl₂/kj) was obtained at the electrical voltage of 15.73 V during 15.63 min in the presence of 63.42 g/l of sodium chloride. The optimum point for current efficiency was 38.40%, which was obtained at the electrical voltage of 10.76 V during 6.70 min in the presence of 34.65 g/l of sodium chloride. Moreover, generated active chlorine was optimized based on energy consumption, which was 77 mg/l for the energy consumption of 0.2 kWh/l at a current density of 2000 mA/cm². The electrochemical production of the chlorine gas from saline or brine water can be extensively used for water disinfection.

本研究调查了通过响应面方法 (RSM) 使用电解从合成盐水溶液中最佳生产活性氯的可能性。评估了各种操作参数，例如氯化钠浓度、电势和电解时间。应用中心复合设计（CCD）来确定氯生产的最佳实验因素。实验设计、数据统计分析和优化使用R 3.5.3软件进行。结果表明，电效率的最佳值（42 mg Cl ₂/kj) 是在 15.73 V 的电压下在 15.63 分钟内在 63.42 g/l 氯化钠存在下获得的。电流效率的最佳点为 38.40%，这是在 34.65 g/l 氯化钠存在下，在 6.70 分钟内，在 10.76 V 电压下获得的。此外，产生的活性氯根据能耗进行了优化，在2000 mA/cm ²的电流密度下，能耗为0.2 kWh/l，能耗为77 mg/l 。从盐水或盐水中电化学生产氯气可广泛用于水消毒。
