Spectrophotometric Determinations of Beryllium and Fluoride Using Chrome Azurol S
- North American Aviation, Inc., Canoga Park, CA (United States). Atomics International Div.
Chrome Azurol S has been applied to the spectrophotometric determination of beryllium and fluoride. The colored beryllium-Chrome Azurol S complex is formed at pH 6.0 in the presence of a pyridine-hydrochloric acid buffer, which enhances the sensitivity of the dye to beryllium and increases the sensitivity of the metal-dye complex to fluoride. With the procedure described, from 1 to 30 μgm of fluoride per 50 mℓ volume can be determined to a precision of 1 μgm, and from 0.2 to 10 μgm or beryllium per 50 mℓ volume can be determined to a precision of 0.2 μgm. Studies were made on the variables of the system, on the interferences, and on an ion exchange method to separate uranium from beryllium.
