Spectral determination of calcium barium and strontium in bio samples food products and water

Gigiena i Sanitariya (11): 100-101
Spectral determination of calcium barium and strontium in bio samples food products and water
A method of determining Ca, Ba and Sr in biosamples, food products and drinking water was developed using the spectrograph ISP-22. Because of the failure of the spark testing system to produce positive results, a generator was substituted with 8 amp current and exposure of 30 s. The solution is pressed into a discharge against the face of a carbon electrode, ground at the surface and preliminarily processed with a 3% solution of polystyrene in benzol. The upper electrode consists of a carbon stem ground to an angle of The preliminary calcination of the upper and lower electrodes was accomplished in an arc of alternating current at 8 amps for 30 s. A solution of Co and nitric acid was used as an internal standard, while the basic calibrating solutions were prepared from spectrally pure Ca salts, Ba and Sr. The concentrations of the elements in the calibrating solutions and the pH of the solutions closely matched the analogous levels in analyzed solutions. The results of parallel determination of Ca, Ba and Sr concentrations by the spectral and chemical methods have a good convergence.
