Bacterial cellulose (BC) is considered an extremely versatile material. With this in mind, its use as a polymer matrix for the production of nanocomposites is increasingly common. In this work, iron-reinforced BC nanocomposites were developed for application as catalysts in the photo-Fenton process, used to degrade the mixture of reactive blue 21 and direct black 22 textile dyes. of cultures Hestrin-Scharamm(traditional) and saline (alternative), noting that the second was less expensive and its use would be more interesting for the suggested application. Then, after obtaining and applying the BC/Fe nanocomposites, it was observed that the material obtained by the ex-situ method showed better catalytic efficiency compared to that produced by the in-situ method. Furthermore, the system employing the best nanocomposite led to a degradation of about 80, 83 and 95%, after 60 min, of the dye mixture, for analysis performed at the accompanied wavelengths of 266, 337 and 664 nm, respectively. Therefore, it can be said that the material developed can be used as a catalyst for treatments that employ the photo-Fenton process. |
