Abstract
A rapid method for the determination of total hydrocarbons in random s amples of oil tanker ballast water is described. A 1-l sample is treat ed with CCl4 after acidification with HCl. The organic extract is anal ysed by measuring features in the zeroth-, first- and second-derivativ e infrared spectra using the Perkin-Elmer SNGLE program and by means o f least-squares curve-fitting algorithms of the zeroth- or first-deriv ative IR spectra using the Perkin-Elmer QUEST program.
