Abstract
The trihalomethane (THM) yield on a total organic carbon (TOC) basis was measured as a function of the molecular weight of precursor organics in the Iowa River. Gel permeation chromatography with Sephadex G-75 gel was utilized to separate naturally occurring organics into apparent molecular weight fractions that were subsequently chlorinated to 2 mg/L of free residual and analyzed for THMs. Ninety percent of the organics in the Iowa River were of mol wt less than 3000, while 75% of the THMs were derived from the mol wt less than 3000 fraction. It was found that bromoform was derived from only the smallest organics of mol wt less than 1700.
