Resumen:
The document describes a chemical method for the determination of nitrilotriacetic acid (NTA), ethylene dinitrilotetraacetic acid (EDTA) and diethylene trinitrilopentaacetic acid (DTPA) in water and waste water in a concentration range from 0,1 to 20 microgram/litre. The substances are complexid by iron ions, separated by liquid chromatography and then quantified by UV-detection.
