Popis:	Developments reported by European research groups in removal of dilute organic pollutants from water under the combined action of TiO2 particles and solar-illumination are briefly outlined. Instances are given of poor correlation between trends actually observed for selected TiO2*-photocatalysed conversion in aerobic conditions and trends expected within the context of two-parameter Langmuir–Hinshelwood-type rate expressions. The necessity of recognising important kinetic roles of several parameters is emphasised not only for aerobic, but also for anaerobic conditions, e.g. TiO2*-photocatalysed conversions of chloromethane pollutants in deoxygenated aqueous solutions. Comparisons between initial TiO2-sensitized photocatalytic degradation (TiO2*-PCD) rates versus dark-equilibrated [C]eq profiles for one strongly-adsorbed and one weakly-adsorbed pollutant in aerated TiO2 suspensions at concentrations
