Colloidal manganese

Colloidal manganese arsenate may be obtained in an analogous way to that described for cadmium and cobalt arsenates.7 If concentrated solutions of manganous chloride and potassium dihydrogen arsenate are mixed at the ordinary temperature, a solid jelly is formed, which remains stable for weeks but finally, rose-coloured crystals separate and the jelly partly liquefies.8 The essential constituent of the jelly appears to be the monohydrogen arsenate, MnHAs04, and the crystals are the monohydrate, MnHAs04.Ha0. [Pg.211]

In the earth environment, colloidal manganese hydroxide has usually a negative electric charge, scavenging cations from the surroundings. Typical cations which react with the surface of the manganese hydroxide colloid are K, Ba, Co, Ca , Li+, NP+, Cu +, Zn +, Pb +, Fe +. ... [Pg.101]

Mn02 colloids have been studied in light-driven systems, using [Ru(bpy)3] " " as photosensitizer and S20g or [Co(NH3)5Cl] as sacrificial agents,as well as in the presence of dark oxidants like Ce(IV). Unfortunately colloidal manganese oxides display poor performance in all these conditions, probably due to the aggregation of initially small particles (6 nm), to yield a physical separation of the catalyst from the reaction mixture. [Pg.282]
