Description
A simple and sensitive method for the spectrophotometric determination of carrier content (Thallium) in 201Tl-TlCl injection is described. Thallium (I) is oxidised to Thallium (III) by aqueous bromine, then excess bromine is removed by adding sulfosalicylic acid. In buffer solution (NH4Cl-NH4OH) at pH 11.7 with the presence of emulsifier OP, thallium (III) and cadion form a complex having an absorption maximum at 469 nm with a molar absorptivity of 1.37 x 104 m2/mol. Beer's law is obeyed in the concentration range of 0-7 μg/5 mL. The effect of impurity elements in 201Tl-TlCl injection is examined. It is an ideal method for the analysis of radioactive solution
