Abstract (EN): This paper reports the development of a method for the determination of Chimassorb 944 (C944), in polypropylene geotextiles, by high performance liquid chromatography with ultraviolet detection. The C944 was removed from the geotextiles by an ultrasonic extraction and then separated in a NH(2) column, followed by UV detection at 244 nm. Analytical validation showed that the method is accurate and precise. The developed methodology was applied for the determination of C944 in geotextiles exposed to artificial UV radiation and to natural weathering. To the best of our knowledge, this is the first method proposed for the determination of C944 in geotextiles.
