    A straightforward method is described for the determination of lithium, sodium and potassium by atomic-emission spectrophotometry on an acidic solution of the sample without separation or concentration. In routine application detection limits of 0, 001 and 001 per cent., respectively, have been obtained with.

    Beryllium interferes seriously in many of the methods available for the determination of trace quantities of lithium. Lithium is selectively separated from beryllium by extraction from 1-M potassium hydroxide solution into M- dipivaloylmethane in diethy1 ether.

SPECTROCHEMICAL DETERMINATION OF BERYLLIUM IN MINERAL BENEFICIATION PRODUCTS by M. Peterson 1 and J. Zink 2 ABSTRACT Spectrochemical methods were developed to determine beryllium in the con­ centration range to percent in siliceous mineral beneficiation products.

Two methods are described. A method is described for the accurate and precise determination of boron, beryllium and lithium in coal ash and geological materials by a point-to-plane high-voltage spark optical emission spectrometric technique.

A mg sample is crushed and blended with graphite, copper oxide internal standard and cellulose powders, and by: 7. Recent studies reported much faster ( min) determination of Be 2+ in stream sediments, 22 and Mg 2+, Ca 2+ and Sr 2+ in seawater 6,23,24 and in saturated brines for the chlor-alkali industry.

Geostandards and Geoanalytical Research29 (2), DOI: /jXtbx. Abstract The use of graphite furnace atomic absorption spectroscopy for the direct determination of traces of beryllium in coal ash is shown to be difficult due to matrix interferences.

The determination of beryllium and lithium in coal ash by inductively coupled plasma atomic emission spectroscopy (ICP-AES) is discussed. Samples were prepared in Parr acid digestion bombs using a mixture of.

S-block elements of the modern periodic table such as lithium and beryllium exhibit unique properties with respect to other elements in the same group due to various reasons. Lithium: Lithium exhibits distinct properties due to the tiny size of the atom, high polarizing power which is a ratio of charge to radius and hydration energy.

This increases the covalent nature of lithium compounds.

Beryllium is also used in the field of X-ray detection diagnostic (it is transparent to X-rays) and in the making of various computer equipment. Beryllium in the environment.

The beryllium content on Earth crust is ppm, in soil 6 ppm. Beryllium in soil can pass into the plants grown on it, provided it. A method for the determination of trace amounts of beryllium has been developed, based on ion-exchange spectrofluorimetry.

Beryllium reacts with morin to give a highly fluorescent complex, which was fixed on a dextran-type anion-exchange resin. The fluorescence of the resin, packed in a 1-mm quartz cell, was measur.

Abstract. A novel procedure for measuring the concentrations of lithium and beryllium in different inorganic and biological samples has been studied using 18 O heavy-ion activation analysis. The specific reactions, 7 Li(18 O,αn) 2c F and 9 Be(18 0,2α) 19 O, are sensitive and selective if the bombardment energy is MeV 18 O 4+.The detection limits for non-destructive analyses are 10 ng Li.

Methods used for the analysis of beryllium in biological materials are reported in Table Reviews of beryllium analysis methods in biological media have been published (Delves ; Tsalev and Zaprianov ). Although the level of beryllium in urine may be. and stream sediments (Rose and others, ).

In arid environments, the sample media selected, in addition to rocks, have generally been stream sediments and heavy-mineral concentrates. The same geochemical techniques and sample media that are used in exploration for favorable mineral environments are.Beryllium ores.
