摘　　要：本文研究了铁电极处理活性艳红染料X-3B。选取不同电流、电导率、pH、电解质和浊度作为影响脱色率的因素,初步探讨了铁电极脱色的机理和反应动力学。结果表明:电流为1A,KCl浓度为2g/L,电解时间为12min时,脱色率高达99.5%,反应机理主要为协同沉淀和吸附作用。The removal of dye of X - 3B was investigated with iron electrodes. Current, conduetivity, pH, electrolyte and turbidity were chosen as effective factors for discoloring and the mechanism of discoloring and reaction dynamics were discussed primarily. The results showed that when the current was 1A with 2g/L KCl in 12min, the removal of dye could reach 99.5%. The primary reaction mechanism was co- precipitation and absorption.
