Laser induced photoacoustic spectroscopy was applied to the determination of 99Tc in a solution coupled with quantitative complexation of Tc with to (thiourea) to form Tc(tu)63+. The complexation procedure was adopted to shift the uv absorption peak of pertechnetate to the visible region. Photoacoustic signals due to the 488 nm absorption peak of Tc(tu)63+ was analyzed by using a Fast Fourrier Transform (FFT) system. The quantitative detection of Tc could be easily performed down to the 10-8 M concentration in this system. This is about 1,000 times more sensitive than the ordinary colorimetric measurement.
