摘要
Abstract
The Ni-Mo-Zr heteropoly salt with Keggin structure has been hydrothermally synthesized and characterized by IR and XRD. Efficiency of ultrasonic degradation of the heteropoly salt for the acidic-green B (AGB) dye as the objective compound was investigated, and the influence factors on the ultrasonic degradation efficiency, such as the amount of the heteropoly salt, the initial concentration and the pH value of the acidic-green B dye wastewater, were explored. The results show that newly synthesized Ni-Mo-Zr heteropoly salt had Keggin structure. When the amount of the heteropoly salt was 0. 8 g/L, the initial concentration of the dye wastewater was 10 mg/L and the initial pH value of the wastewater was 5.0, and ultrasonic irradiation was carried out for 60 min at 40 kHz, the degradation rate was optimum and up to 90.2%. After dynamics analysis, it showed the degradation reaction was in accord with the first order dynamics model, and the degradation rate was decreased with the increasing of the initial concentration of the acidic-green B.关键词
