SummaryAnhydrous hydrogen chloride, which is far more reactive than concentrated aqueous hydrochloric acid, is formed when solid zinc chloride or evaporation residues of its solutions are heated. Certain reactions, which cannot be accomplished with the concentrated aqueous acid, can be realized by fusion with zinc chloride. Detection of calcium, magnesium, ferrous iron, nickel, and potassium in silicates; differentiation of niobium and tantalum pentoxides, can be based on the ready…

The common but unexpectedly neglected natural particle suspensions (NPSs) have significant effects on the characteristics of molten salts. In the present work, NPSs were generated via the corrosion
A clean process for activator recovery during activated carbon production from waste biomass
Abstract Chemical activation is a widespread method for activated carbon (AC) preparation, but the removal and recycle of activator from the carbon product are generally a nuisance process. In this
