Abstract
A new reagent namely 3,4-Dihydroxybenzaldehyde Thiosemicarbazone (3,4-DHBTSC) synthesized by the authors for the determination of uranium(VI) in monazite sand, pitchblend ore, spiked water, human hair and human blood samples. A brown colored complex was formed between uranium(VI) and 3,4-DHBTSC in a media of pH 7. The developed method can be conveniently applied for the analytical determination of uranium (VI) in the concentration range 0.476 – 4.760 μg/ml. The molar absorptivity and sandell`s sensitivity were found to be 2.0833x104 L/mol/cm and 0.0114 μg/cm2 respectively. The proposed method was found to be linear (R>0.01), selective, accurate (recovery=<99.7%) and precise (RSD<1.1%) in the reported linear calibration line.
