Abstract

Wet ashing, substrate decolorization, and a solvent extraction approach were all tested in an attempt to quantify the retention of [14C]2,4-dichlorophenol and [14C]2,4,5-trichlorophenol by pulped wood fibers. Development of a method for determining the mass of fiber contained in counting vials as part of the solvent extraction approach allowed experiments to be carried out using small quantities of fiber. The combination of solvent extraction and this mass determination method produced recoveries of > 98%, proving it to be the superior approach.
