In this work, the decolorization efficiency of Reactive Red 120 (RR120) synthetic solution using ferrioxalate (CuOFeB) and Al, Fe-bentonite (AlFeB) catalysts in the solar-assisted Fenton process was evaluated, as well as impact of H₂O₂ photolysis on the process efficiency.The photo-Fenton oxidation of dye has been investigated using a concentrating solar parabolic reactor with constant solar radiation of 550 W/m² and 950 W/m² for spring and summer periods, respectively. Experimental data has proved that photolysis of hydrogen peroxide has an important role in the process of decolorization, achieving a decolorization efficiency over 80.78% at pH 7. Under the optimal reaction conditions, both catalysts showed a good stability in the processes with dye removal over 90%. The mineralization efficiency depends on the intensity of the solar radiation, wherein ∼50% was achieved under the higher solar intensity. Comparing reaction rate it is important to note that the larger specific surface area of AlFeB (155.83 m²/g) makes him a superior catalyst and thus solar-assisted Fenton process with this catalyst fast and efficient. Based on the decolorization rate constants, the examined processes can be placed in the following order: AlFeB (950 W/m²) > AlFeB (550 W/m²) > CuOFeB (950 W/m²) > CuOFeB (550 W/m²). These findings are confirmed on real effluent, whereby a greater degree of decolorization (91.89%) and mineralization (43%) has been achieved with AlFeB catalyst compared to CuOFeB (30.09% and 15%) during the process.

在这项工作中，评估了在阳光辅助的Fenton工艺中使用草酸亚铁（CuOFeB）和铝，铁膨润土（AlFeB）催化剂的活性红120（RR120）合成溶液的脱色效率，以及H ₂ O _2的影响。使用浓缩的太阳能抛物线反应器研究了染料的光芬顿氧化，该抛物线反应器的恒定太阳辐射为550 W / m ²和950 W / m ²分别在春季和夏季。实验数据证明，过氧化氢的光解在脱色过程中起着重要作用，在pH值为7时，脱色效率超过80.78％。在最佳反应条件下，两种催化剂均显示出良好的稳定性，染料去除率超过90 ％。矿化效率取决于太阳辐射的强度，其中在更高的太阳强度下可达到约50％。比较反应速率时，重要的是要注意，较大的AlFeB比表面积（155.83 m ²/ g）使他成为一种优异的催化剂，因此快速，高效地利用了太阳助燃的Fenton工艺。基于脱色速率常数，可以按以下顺序放置检查的过程：AlFeB（950 W / m ²）> AlFeB（550 W / m ²）> CuOFeB（950 W / m ²）> CuOFeB（550 W / m ²）。这些发现在实际废水中得到了证实，与过程中的CuOFeB（分别为30.09％和15％）相比，AlFeB催化剂已实现了更大程度的脱色（91.89％）和矿化（43％）。
