%X Cooperating with oxidation(H2O2),tourmaline can efficiently make the argazol blue BF-BR dyeing wastewater decolored.The decoloration rate of argazol blue BF-BR increases,with tourmaline dosage,oxidation dosage,temperature and contact time increasing.At pH=2 and 12,decoloration rate reaches maximum.Through orthogonal experiments,the optimum condition can be concluded that oxidation dosage is 1.5 mL,contact time is 9 min,tourmaline dosage is 1 g,temperature is 363 K and solution pH is 2.Under the optimum condition,the decoloration ratio can come up to 100%.Kinetic research indicates that the decoloration reaction of argazol blue BF-BR accords to one order kinetic reaction,and the kinetic equation can be described as follows:-lnCR=0.36733t-lnC0(R=0.9827),with reaction rate constant k=0.36733 min-1 and half life t1/2=1.887 min.Mechanism analysis shows that mineral-catalyzed Fenton-like reaction results in the decoloration of argazol blue BF-BR dyeing wastewater.
