✦ Synopsis
A rapid method for the determination of total hydrocarbons in random samples of oil tanker ballast water is described. A l-l sample is treated with CCl, after acidification with HCl. The organic extract is analysed by measuring features in the zeroth-, first-and second-derivative infrared spectra using the Perkin-Elmer SNGLE program and by means of least-squares curve-fitting algorithms of the zeroth-or first-derivative IR spectra using the Perkin-Elmer QUEST program.
