Component concentration of sodium aluminate solution is an important quality index for alumina production. In this article, we propose a new on-line soft sensing strategy for measuring component concentration of sodium aluminate solution. With this method, on-line control can be realised in aluminate production plants. Several advance techniques are used, such as principal component analysis (P...

effluent from ro (reverse osmosis) systems during recovery gradually becomes concentrated and supersaturated with soluble salts such as calcium carbonate (caco3), calcium sulfate (caso4), barium sulfate (baso4) and silica (sio2). thus we were looking for procedures to prevent precipitation of soluble salts on the membrane surface and decrease membrane permeability. therefore, recovery could be ...

a type of zeolite from the analcime family was prepared by using triethanolamine, silica gel and sodium aluminate. the average particle size was around 24 µm. ftir, xrd and sem results approved the type of zeolite which was formed

The desilication effects of aluminium sulphate and sodium aluminate on kraft bamboo pulp during the cooking process were investigated in this study. Furthermore, the residual aluminium ion concentration in the resulting black liquor was measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) to evaluate the scaling properties of black liquor during the evaporation process....

A modified commercial (Setaram C80) calorimeter has been used to measure the isobaric volumetric heat capacities of concentrated alkaline sodium aluminate solutions at ionic strengths from (1 to 6) mol kg, with up

A significant improvement in the production of l-ribulose from inexpensive and commercially available starting materials, L-arabinose and sodium aluminate, is demonstrated. This has facilitated expeditious access to gram-scale quantities of L-ribulofuranoside derivatives.

"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...
