Abstract
Abstract Morpholine and its amine breakdown products in aqueous samples were derivatized with dabsyl chloride in the presence of sodium bicarbonate and the resulting precolumn derivatives determined by high-performance liquid chromatography with visible detection at 456 nm. The analytical column was a μBondapak C18 reversed-phase device. The breakdown products were determined in the concentration range of 0.25–10 μg/ml in water, with a relative standard deviation of 0.38–7.08%. The amine detection limits were 0.01–0.03 μg/ml for 20-μl injections. Chromatographic analysis of 100-ml grab samples after acidification and concentration demonstrates the sucess of this technique for determining the quantity (ng/ml) of ammonia, methylamine, ethylamine, ethanolamine and 2-(2-aminoethoxy)ethanol in the thermal cycle at Gentilly 2 nuclear power plant. The recovery for the complete assay procedure varied between 92.0 and 106.0% depending on the product studied.
