Photoacoustic spectrometry was applied to the determination of michroamount of Hg diphenylcarbazone complex. The photoacoustic spectrum and diffuse reflectance spectrum almost agree with each other, showing an absorption maximum at 560 nm, as in the absorption spectrum of the complex in benzene solution. Determination of Hg was performed by measuring the intensity of photoacoustic signal at 560 nm. The normalized signal intensity increased linearly with the amount of mercury ion up to 100 ng, deviating from linear relationship downwards above 100 ng. The photoacoustic signal saturation caused by strong absorption of radiation was investigated.
