When the contents of the anode and the cathode chambers were mixiing , producing ferrous hydroxide in solution which chemically reacts with dye and coprecipitates to remove more than 88 % of color and organics. Reduction in voltage and increase in electrolysis time in the same electric quantity would rise efficiency. The solution , after electrolysis , controlled in the weak acid also rise decoloring efficiency. Three different types of dye were treated . The best efficiency of electrolysis is BWS direct dye , then is RS/HC acid dye and the worst is H-E3B reactive dye. The electrolysis of potassium chloride solution using山 type groove would produce little hypochlorous acid to oxidize dye. Application of streaming current technique to determine the best dose is done. The three different concentration ,100、200、300 ppm,dye solution were treated at pH 3. The streaming current readings controlled between -0.12 and -0.18 gains the best cogulation result. If the solution contains electrolyte streaming current readings will be interferenced and refer no relation to decoloring. Kung Tu Kuo 郭坤土 1993 學位論文 ; thesis 68 zh-TW
