Characterization of Organic Components in Wastewater from Coke Oven, Using High Performance Liquid Chromatography (HPLC)

Abstract

Organic components in the wastewater from the cokeoven were Suc-cessfully and rapidly characterized with HPLC, using a ultrahydrogel column and H₂O/CH₃CN (40‰) mixed solvent. The organic components were found to consist of seven fractions which appeared to be separated according to their molecular weight as observed with gel chromatography. 40‰ CH₃CN was selected because of stable base-line and adequate elution time. NaNO₃ was found to disturb the separation although seawater was useful as a part of the solvent.
The present characterization procedure may be applicable to wastewater of various origins from the coke oven before and after the chemical as well as biological treatment.
