Simultaneous spectrophotometric estimation of thorium and calcium in urine
- 1. Indira Gandhi Centre for Atomic Research, Kalpakkam (India)
Description
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-wave-length linear regression analysis procedure was applied. Thorium recovery was found to be 78.3% ± (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/dm3. The analytical results of calcium agree very well with those determined by EDTA titrimetry. (Author)
