With reference to alkaline metals, the amount, [M.sub.r], of sodium or potassium ions released or accumulated at the testing time, t, can be calculated by the following equation:
Assuming that equilibrium conditions are approached and there is no binding of alkaline metals by the solid phase of the cement paste, the following balance equation can be written, with reference to the alkaline metal under consideration:
Among their topics are the ion-exchange kinetics of alkaline metals on the surface of carboxymethyl cellulose Sn(IV) phosphate composite cation exchanger, the adsorption of proteins onto non-soluble polysaccharide matrices: a friendly strategy to isolate enzymes with potential application for downstream processes, different desalinization processes for turning sea water into fresh drinking water, removing phosphates and sulphates in a multi-ion system with nitrates, and adsorption and ion exchange: basic principles and their application in food processing.
Gases, alkaline metals and other elements are simply too unstable or difficult to smelt.
A Period begins with an element the atom of which contains one s-electron at the outer level: this is hydrogen in Period 1, and alkaline metals in the others.
Group I contains alkaline metals having very strong chemical activity, but simultaneously the sub-Group "b" contains copper, silver and gold which have not these properties but possess excellent electric conductivity.
Taking into account the results obtained, it was assumed that if to use as a porophore halogenides of alkaline metals with different values of the melting point, it will be possible to change temperature conditions, at which condensates with maximal porosity will be formed.
Methodology of deposition of porous condensates in electron beam evaporation and joint deposition of the stainless steel vapor phases and the alkaline metal halogenide on a preliminarily heated up to a certain temperature substrate is described in detail in [3].
That allows to assume that water-soluble chemical compounds (chlorines and sulphates of alkaline metals and free CaO), initially present in ash, have mostly been leached and carried away from the ash field with precipitation water.
For example, the elements of Group 1 are alkaline metals (the very active chemical elements), while Group 18 consists of inert gases which manifest a very low chemical activity under the regular physical conditions.
Four groups of minerals containing alkaline metal (Cs or Na and /or K) were selected for water leaching test.
