Abstract
A safer, low-cost practical method of dissolving beryllium or a beryllium compound including beryllium oxide in a sample is disclosed. This method discloses use of acidic solutions under mild heating conditions to dissolve beryllium and its compounds. These solutions may then be used to quantitatively analyze for beryllium so as to be able to determine the amount of beryllium in the sample. These solutions may also be combined with fluorescent dye indicating solutions to determine beryllium by fluorescence. A preferred fluorescent dye indicating solution contains a dye (10-hydroxybenzo[h]quinoline-7-sulfonate) which specifically binds with beryllium under basic conditions.
