Chemical effects include stable compound formation and ionization, both of which decrease the population of free atoms in the sample vapour and thereby lower the measured absorbance. Examples of compound formation include reactions between alkaline earth metals and oxyanions such as aluminates, silicates and phosphates, as well as the formation of stable oxides of aluminium, vanadium, boron etc. [Pg.332]

Cement binders are based on silicates, aluminates, aluminium silicates, aluminium ferrites of alkaline earth metals (mainly calcium). The hydration of these compounds or their mixtures with the formation of... [Pg.188]

Consider the case of determining alkaline and alkaline-earth concentrations. The catalyst samples where the matrix is alumina or a zeolite are reduced to a powder and dissolved in hydrochloric acid solution either by direct attack by high purity acids or after fusion with lithium metaborate. The choice of acids used to attack the samples depends both on their composition (alumina or aluminium silicate) and on the active elements present. Success of the method in forming a solution depends partly on the information available on the composition of the sample. If the presence of certain elements is not known, it may be necessary to test several methods prior to obtaining a satisfactory dissolution. [Pg.53]

By the treatment of crude, alkaline polyethers, in the presence of water (1-2% against the polyether), with solid adsorbents (1-3% against the polyether) such as aluminium silicates (montmorillonite type, bentonites, activated Fuller s earth) and magnesium silicate (Magnesol) [132,133], the potassium ion is efficiently retained on the solid surface by adsorption. The high surface area of these adsorbents, i.e., 100-250 m2/g, helps the adsorption efficiency. [Pg.131]

The atomic absorption technique provides one of the most sensitive and convenient methods of determining magnesium in solution. Allan, David and Willis have shown that a sensitivity limit of about OT p.p.m. can be reached and there is little difficulty in determining 1 p.p.m. or even less. The only serious interferences are from silicate, phosphate, aluminium and sulphate but these are eliminated according to David if calcium (or presumably any other alkaline earth element) is present in the solution. [Pg.390]
