The paper briefly reviews the status of titanium as an environmental pollutant and presents a new method suitable for the microdetermination of the metals in plants, animal tissues and waters. The method is based on extractive separation of titanium as its chelate with N-p-methoxyphenyl -2-furylacrylohydroxamic acid (MFHA) in chloroform or isoamyl alcohol and subsequent spectrophotometric or atomic absorption spectrometric determination. MFHA was chosen from nine new hydroxamic acids as detailed in the paper. The overall sensitivity of the spectrophotometric method with chloroform as extracting solvent i s better than 1 ppb (0.001 ppm). For atomic absorption spectrometric determination isoamyl alcohol is used as extracting solvent and a sensitivity of 0.2 ppm, which is ten times better than attained earlier, is achieved. There was excellent agreement between the results obtained by the two different instrumental methods.
