A comparison of some methods for the determination of triazine herbicides in water

By using gas chromatography with an alkali flame detector, 0·001 p.p.m. of atrazine, ametryne and terbutryne in water from two sources could be determined with recoveries close to 100 per cent. Ultraviolet spectrophotometry was adequate at the 0·01 p.p.m. level for all three compounds but was unreliable at lower levels. With cathode-ray polarography, 0·005 p.p.m. of terbutryne and ametryne and 0·01 p.p.m. of atrazine could be determined.
