Effluent containing tartrazine can affect the environment and human health significantly prompting the current study into degradation using a sonochemical reactor operated individually and combined with advanced oxidation processes. The optimum conditions for ultrasound treatment were established as dye concentration of 10 ppm, pH of 3, temperature as 35 °C, and power as 90 W. The combination approach of HO/UV, HO/US, and HO/UV/US resulted in higher degradation of 25.44%, 57.4%, and 74.36% respectively. Use of ZnO/UV/US approach increased the degradation significantly to 85.31% whereas maximum degradation as 93.11% was obtained for the US/UV/Fenton combination. COD reduction was found maximum as 83.78% for the US/UV/Fenton combination. The kinetic analysis showed that tartrazine dye degradation follows pseudo first-order kinetics for all the studied processes. Combination of Fenton with UV and US was elucidated as the best approach for degradation of tartrazine.
含有柠檬黄的废水会对环境和人类健康造成重大影响，因此本研究采用单独使用和与高级氧化工艺联合使用的声化学反应器对其进行降解。超声处理的最佳条件为：染料浓度为 10ppm，pH 值为 3，温度为 35°C，功率为 90W。HO/UV、HO/US 和 HO/UV/US 的组合方法分别导致 25.44%、57.4%和 74.36%的更高降解。使用 ZnO/UV/US 方法可使降解率显著提高至 85.31%，而 US/UV/Fenton 组合则可获得最高的 93.11%的降解率。COD 去除率最高的是 US/UV/Fenton 组合，达到 83.78%。动力学分析表明，所有研究过程中，柠檬黄染料的降解均遵循准一级动力学。芬顿试剂与 UV 和 US 的联合被阐明为降解柠檬黄的最佳方法。
