Measurements of adsorption isotherms of a series of thirteen mono- and di-phosphonic acids have shown that these bind strongly to the surface of high surface area aluminium trihydroxide. The incorporation of such phosphonates into a suspension of aluminium flake in an aqueous medium, modelling the continuous phase of a water-based paint, greatly suppresses the evolution of hydrogen. Whilst stro...

In the crystal structure of the title salt, 3C(5)H(6)NO(+)·HSO(4) (-)·SO(4) (2-)·H(2)O, the hydrogen sulfate ion is linked to the sulfate ion by an O-H⋯O hydrogen bond. The hydrogen sulfate-sulfate anion is a hydrogen-bond acceptor for the three independent cations and the uncoordinated water mol-ecule, the hydrogen-bonding inter-actions giving rise to a three-dimensional hydrogen-bonded networ...

Flocculation with titanium tetrachloride (TiCl(4)) and titanium sulfate (Ti(SO(4))(2)) was investigated in terms of different coagulant doses, pH, turbidity, dissolved organic carbon (DOC), UV-254, colour, zeta potential, particle size and molecular weight distribution. The two coagulants were compared with the commonly used coagulants such as ferric chloride (FeCl(3)) and aluminium sulfate (Al...

Background: Aluminium dross is a valuable resource that is often redirected to landfill as there are no real viable solutions for the utilisation of this industrial waste. A study has been conducted to provide a recycling process where the dross is reacted with an alkaline solution in order to generate hydrogen with bayerite and gibbsite products. Methods: Samples of aluminium dross were obtain...

"Aluminium hydroxide dissolves in acids. From its solution in hydrochloric acid, an aluminlum salt, aluminium chloride A1C13, 6H20, is obtained. I t also combines with strong bases, dissolving for instance in a solution of sodium hydroxide and forming an aluminate, NaA102 . . . . According to the best knowledge we have on the subject, the molecule of aluminium hydroxide has the following struct...

aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

in this research, we have developed cheap recyclable and task-specific acidic ionic liquids (ails) 1-hydrogen-3-methylimidazolium hydrogen sulfate [hmim]hso4, 1-hydrogen-3-methylimidazolium chloride [hmim]cl, 2-pyrrolidonium hydrogensulfate [hnhp]hso4 and applied them in acid catalyzed synthesis of quinoxaline derivatives from 1,2-phenylendiamines and 1,2-dicarbonyl compounds. the products coul...

The presence of excess hydrogen at the interface between a metal substrate and a protective oxide can cause blistering and spallation of the scale. However, it remains unclear how nanoscale bubbles manage to reach the critical size in the first place. Here, we perform in situ environmental transmission electron microscopy experiments of the aluminium metal/oxide interface under hydrogen exposur...
