Methyl Violet Degradation by Bamboo Charcoal/Microwave Method

Abstract:

In the paper methyl violet degradation by bamboo charcoal-microwave irradiation method was researched. The main parameters which were studied including the amount of bamboo charcoal, H₂O₂ dosage, FeSO₄·7H₂O dosage and time of microwave irradiation were investigated. The UV-visible spectra of methyl violet were determined. The results show that: under bamboo charcoal, H₂O₂ and FeSO₄·7H₂O microwave condition the degeneration rate of methyl violet was almost 100%. The increase of bamboo charcoal dosage can accelerate the reaction process, speeding up the degradation of methyl violet. The increase of H₂O₂ may provide more ·OH and speed up the reaction process, but when up to a certain amount, the influence is weakened. The lengthening of microwave time may enhance the reaction temperature, and urge the methyl violet to degrade completely. For 0.2 g·L^-1methyl violet 4:9 diluted, by adding 0.5g bamboo charcoal, 1 mL 36% H₂O₂, 1 mL FeSO₄·7H₂O of 1mol·L^-1 and under mesotherm microwave for 30s, the methyl violet can be all degradated.
