Iron, manganese and aluminium oxides and

2013-1-1  Nanosized iron, manganese and aluminium oxides are abundant in soils and sediments, but are also present in water and air, and are even produced within living organisms. These minerals play major roles in the biogeochemical cycles of Fe, Mn and Al; the adsorption and transport of ions, including nutrients and toxic metals; and redox processes.

A particle-scale reduction model of copper iron

2020-3-15  Successful implementation of CLC technology depends highly on the behavior of the OC in the system. Thus, an understanding of the reaction mechanisms that take place inside a CLC reducing reactor with a high-performing OC, such as copper iron manganese oxide (CuFeMnO 4), is critical for CLC reactor design and scale-up.

Removal of iron and manganese from drinking water

2015-8-14  The removal of iron and manganese was not significant at lower doses of chlorine (5 and 10 mg/L). At 15 mg/L of chlorine dose with a contact period of 5 h at pH 8.0–8.9, there was significant removal of iron and manganese (Table 5). It is apparent that oxidation of iron and manganese depends on the holdup time, pH and chlorine concentrations.
