从图5a中可以看到，催化剂剂量与四环素降解速率成正相关关系。在800W

It can be seen from Figure 5a that the catalyst dosage is positively correlated with the degradation rate of tetracycline. Under the same microwave power of 800W, the degradation rate and amount of tetracycline both increase with the increase of the catalyst dosage. The experimental results show that in the absence of a catalyst, microwave radiation can directly induce more than 70% of the tetracycline to degrade within 30 minutes of reaction time. When the catalyst dosage is less than or equal to 50mg, although the degradation rate of tetracycline is increased, it cannot be completely degraded within 30 minutes. When the dosage of the catalyst is increased to 100 mg or more, it can be found that the degradation reaction mainly occurs in the first 5 minutes, and almost complete degradation of tetracycline can be completed in the first 15 minutes of the reaction, and the degradation rate of tetracycline is greatly improved. The degradation rates of 100mg and 200mg catalysts are very close. Considering cost factors, a catalyst dosage of 100mg is considered to be the most suitable catalyst dosage.

As can be seen from Figure 5a, the catalyst dose is positively related to the rate of cyclictin degradation. At the same microwave power of 800W, the degradation rate and degradation of tectontatin increase with the increase of catalyst dose. The experimental results show that microwave radiation can directly induce the degradation of more than 70% of tectontatin in 30min reaction time without catalyst. When the catalyst dose is less than or equal to 50 mg, the degradation rate of tyrenine is increased but cannot be completely degraded within 30min. When the catalyst dose is increased to 100 mg or more, it can be found that the degradation reaction occurs mainly in the first 5min, and the first 15min of the reaction can almost complete the complete degradation of tycylin, the degradation rate of tyrene is greatly increased. The degradation rate of 100mg and 200mg catalysts is very close, and the 100mg catalyst dose is considered to be the most suitable catalyst dosage for cost considerations.

It can be seen from Fig. 5A that there is a positive correlation between catalyst dosage and tetracycline degradation rate. The degradation rate and amount of tetracycline increased with the increase of catalyst dosage at the same microwave power of 800W. The results show that microwave irradiation can induce more than 70% tetracycline degradation in the absence of catalyst in 30 minutes. When the catalyst dosage is lower than or equal to 50mg, the degradation rate of tetracycline can not be completely degraded in 30min, although the degradation rate of tetracycline has been increased. When the catalyst dosage increases to 100mg or more, it can be found that the degradation reaction mainly occurs in the first 5min, and the complete degradation of tetracycline can be completed almost 15 minutes before the reaction, and the degradation rate of tetracycline is greatly increased. The degradation rate of 100mg and 200mg catalyst is very close. Considering the cost factors, 100mg catalyst dosage is considered as the most suitable catalyst dosage.<br>
