Reusability study of fenton catalyst@bacterial celluloses for removal of methylene blue as synthetic dyes model Available to Purchase

Heterogeneous fenton catalyst is one of the promising technologies for destruction of persistent and non-biodegradable pollutant in wastewater, such as dyes from textile industries. Previously, bacterial celluloses (BCs) were used as catalyst support of fenton catalysts to improve their catalytic activity. However, reusability of fenton catalyst@bacterial celluloses were not explored yet. Herein, fenton catalyst@bacterial celluloses were prepared using sol gel method with precursor concentration of 0.05 M and characterized by visual observation, Scanning Electron Microscopy (SEM) and UV-Vis spectroscopy. After five cycles of repeated use, catalytic ability of the catalysts was gradually decrease to 17.9% of the original one. Understanding reusability of fenton catalyst@bacterial celluloses will be helpful for wastewater treatment application.
