Synthesis, application and mechanisms of Ferro-Manganese binary oxide in water remediation: A review

In recent years, water pollution has been attracted public attention being that its harm to human and ecology. Ferro-Manganese binary oxide (FMBO) with the characteristics of much active sites and high affinity to contaminants has been widely applied in wastewater treatment. This paper aims to review FMBO and its ramification, collectively named as FMBO-based materials to remove various pollutants from polluted water. Firstly, the synthesis methods of FMBO-based materials ware summarized and indicated that co-precipitation was the most common method. Secondly, the application of FMBO-based materials in water treatment was introduced emphatically. Thirdly, the influence factors refer to pH, coexisting ions and the physicochemical properties of FMBO-based materials ware also concluded. Moreover, the mechanisms including adsorption, redox and degradation were also discussed comprehensively and deeply. Finally, future researches on FMBO-based materials were also proposed such as toxicity of FMBO-based materials in practical environmental remediation, modifying potential waste by FMBO to realize the utilization of resources, composite catalytic system as to the synergistic mechanism, application in other refractory organic pollutants and application in soil remediation.
