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, H2O2dosage, 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, H2O2and 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 H2O2may 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-1and under mesotherm microwave for 30s, the methyl violet can be all degradated. |
