Summary

The control of water quality is often performed by analysis of organic group parameters, e.g., “Adsorbable Organic Halogen (AOX)”. The differentiation of the group parameter AOX and the determination of the parameter “Adsorbable Organic Sulfur Compounds (AOS)” can be performed by ion-chromatography for detection of the anions obtained after pyrohydrolysis of the organic adsorbed compounds. Investigations concerning pyrohydrolysis of organic solutes and enrichment on a nearly chlorine- and sulfur-free active charcoal have been performed. By means of this charcoal the determination of organic sulfur solutes in the μg/l range can be realized.
