Abstract

This is the first record on literature to use biochar as support for CoFe2O4 to applicate and evaluate it as photocatalyst for degradation of organic pollutants. The support was verified by XRD, FT-IR, SEM, EDS and band gap. Composites CFO1BQ3, CFO1BQ1, and CFO3BQ1 showed 100% degradation in 60 min. This outstanding performance can be related to the drop in band gap energy and recombination rate of e¯/h + . The composites showed better efficiency when compared to pure CoFe2O4 (∼78%). This might be associate to the fact that biochar has a high concentration of phenolic, hydroxyl and carboxylic functional groups on its surface. In this reaction h+, O2•-, and •OH were the reactive species involved in the degradation. The toxicity of ponceau was tested before and after the treatment, through biochemical biomarkers in Danio rerio fish. In general, the treatment proved to be efficient in reducing ponceau toxicity in D. rerio fish.

使用新型 CoFe2O4/ 生物炭光催化剂复合材料处理含有有机污染物的废水并评估其生态毒性。
这是文献中首次记录使用生物炭作为 CoFe2O4 的支持物,以应用和评估其作为光催化剂降解有机污染物的效果。X射线衍射、傅立叶变换红外光谱、扫描电子显微镜、电致发光和带隙对支撑物进行了验证。复合材料 CFO1BQ3、CFO1BQ1 和 CFO3BQ1 在 60 分钟内 100% 降解。这种出色的性能与带隙能的下降和 e¯/h + 的重组率有关。与纯 CoFe2O4 相比,复合材料的效率更高(78%)。这可能与生物炭表面具有高浓度的酚醛、羟基和羧基官能团有关。在这一反应中,h+、O2--和 -OH 是参与降解的活性物种。在处理前和处理后,通过对 Danio rerio 鱼体内的生化生物标志物检测了 ponceau 的毒性。总的来说,这种处理方法被证明能有效降低龙鱼体内的龙葵素毒性。
