Under the condition of 278 ~ 297 K, as the initial solution temperature increases, the degradation rate of azoxystrobin increases. Under the condition of 297 ~ 343 K, as the initial solution temperature increases, the degradation rate decreases significantly. This is because the temperature rises, the mass transfer rate of the active particles in the gas to the liquid increases. But at the same time, the bubble expands by heating, and the time to escape the liquid becomes shorter. In other words, the mass transfer time is significantly shorter. Lead to poor mass transfer effect. In general, under the condition of 278 ~ 297 K, the initial solution temperature increases slightly (the temperature difference is 19 K), and the mass transfer rate has a greater influence on the mass transfer effect than the thermal effect (gas thermal expansion). , So the degradation effect gradually becomes better;
