ABSTRACT
This technique has been applied predominantly to organic and organometallic compounds with a small number of applications to cations and anions.

Brown and Rhead [1] determined down to 0.2ug L _ 1 amides in non saline waters by high performance liquid chromatography. The procedure consists of bromination, extraction of the a,p-dibromopropionamide produced with ethyl acetate and quantification using high performance liquid chromatography with ultraviolet detection. Samples tested included river, sea and estuarine waters, sewage and china clay works effluents, and potable waters. The levels of inorganic ultraviolet absorbing impurities found in water samples did not interfere in this procedure. The experimental yields of a,p-dibromopropionamide encountered gave a mean of 70.13 ± 8.52% (95% confidence level) for acrylamide-spiked waters, over the concentration range 0.2-8.0pg L _ 1 of acrylamide monomer.
