Ferrous poisoning of surface MnO2 during manganese greensand operation

Journal of Environmental Chemical Engineering, 2017
This study investigated the fundamental performance of manganese greensands for the removal of both dissolved manganese and iron species from solution. The hypothesis was that iron ions may detrimentally impact manganese removal and that the magnitude of

The Effect of SO₂ on C₃H₈ Oxidation over Ru@CoMn₂O₄ Spinel [PDF]

Molecules
Propane is a typical volatile organic compound (VOC) in coal chemical processing and petroleum refining. However, coexisting SO2 significantly impairs its catalytic oxidative removal, potentially causing catalyst poisoning and deactivation.

Manganese Poisoning in Moroccan Miners [PDF]

Occupational and Environmental Medicine, 1955
While there is very little in the literature about criminal or accidental manganese poisoning, man ganese ores and their industrial applications give rise to a number of cases of occupational poisoning. The historical background of the condition has already been reviewed in a previous paper (Rodier and Rodier, 1949) but it should be noted that this ...

Electrocatalysis by nanoparticles: Oxidation of formic acid at manganese oxide nanorods-modified Pt planar and nanohole-arrays

Journal of Advanced Research, 2010
The electro-oxidation of formic acid (an essential reaction in direct formic acid fuel cells) is a challenging process because of the deactivation of anodes by the adsorption of the poisoning intermediate carbon monoxide (CO).
