Degradation of two different kinds of dyes, anthraquinone Reactive Blue 4 (RB4) and azo Reactive Black 5 (RB5), by low-cost zero valent iron (Fe(0)) in a N(2) bubbling system (Fe(0)/N(2) process) and air bubbling system (Fe(0)/air process) was investigated. The operating parameters, including initial solution pH, dye concentration and Fe(0) dose, were also evaluated. The Fe(0)/air process shows a higher decolorization rate compared to the Fe(0)/N(2) process. Both RB4 and RB5 solutions at 100 mg… CONTINUE READING
