Gas-liquid chromatographic determination of bromacil residues.
A simple, fast, and accurate method has been developed to determine residues of bromacil (5-bromo-3-sec-butyl-t-methyluracil) herbicide. Following sample extraction, filtration, and concentration, the herbicide is determined using a gas chromatograph equipped with a thermionic nitrogen/phosphorus detector. The method has been used to recover 0.04 ppm bromacil added to citrus, pineapple, soil, and water, and 0.1 ppm bromacil added to alfalfa hay.
