-N=C&N-, have been known to react as bidentate ligands with certain metal ions such as ferrous, cuprous, and cobaltous, to give colored complex species (1-6). This effect was first noticed with the ferrous ion ( I ) , and since this complex of a given compound is generally of a more intense color than are those with other ions (7), the atomic configuration in question was given the trivial name...

BACKGROUND Recently developed iron cocatalyst enhancement of dilute acid pretreatment of biomass is a promising approach for enhancing sugar release from recalcitrant lignocellulosic biomass. However, very little is known about the underlying mechanisms of this enhancement. In the current study, our aim was to identify several essential factors that contribute to ferrous ion-enhanced efficiency...

Waste water purification is shown to be an important field of environmental hygiene for non-ferrous metal industries. Hydrometallurgy becomes of greater importance for metal production and refining. Quality standards for drinking water and rivers require a minimum of some harmful impurities, e.g. metal compounds. The unit operations of hydrometallurgy technologically parallel the methods of eff...
