Abstract
A method of determining beryllium or a beryllium compound in a sample is disclosed by measuring fluorescence. This method discloses use of highly strong acids to extract beryllium from samples into the acidic medium, and then using these solutions in combination with highly alkaline fluorescent indicating dye solutions to determine the amount of beryllium in the samples.
