Abstract: The chlorine bubble size and distribution electrolytically evolved from DSA/NaCl system were investigated by means of Laser diffraction method. An increase of bubble diameter with increasing current density was observed in the range of 50-300mA/cm2. Electrode orientation and geometry both affected bubble size. When brine concentration was decreased, chlorine bubble diameter became smaller. The results showed that for multi-bubbles system, bubble coalescence might largely determined the bubble size and its distribution.

摘要： 采用激光衍射法研究了DSA/NaCl体系电解析出的氯气泡大小及其分布特点.发现在50～300mA/cm~2区间内电流密度提高,氯气泡增大;电极的取向和结构是影响气泡大小的重要因素;NaCl浓度减小时气泡减小.研究表明,对于多气泡体系,气泡的聚并与电解气泡的大小及分布有密切关系.
