Simultaneous spectrophotometric estimation of thorium and calcium in urine

A simple and rapid method for the simultaneous estimation of thorium and calcium in urine was developed. Thorium and calcium were coprecipitated as oxalates at pH 3–4 and were determined using Thoronol as reagent. A multi-wavelength linear regression analysis procedure was applied. Thorium recovery...

Summary:A simple and rapid method for the simultaneous estimation of thorium and calcium in urine was developed. Thorium and calcium were coprecipitated as oxalates at pH 3–4 and were determined using Thoronol as reagent. A multi-wavelength linear regression analysis procedure was applied. Thorium recovery was found to be 78.3%±5.1% (1 σ) and that of calcium was 93.7±3.0% (1 σ). The minimum detection limit for thorium was found to be 2.54 mBq/dm 3. The analytical results of calcium agree very well with those determined by EDTA titrimetry.
