MODIFIED STRIPPING TECHNIQUE FOR THE ANALYSIS OF TRACE ORGANICS IN WATER

A modification of closed loop stripping analysis that reduced the problem of contamination of the standard system was reported. This modification also made the system more flexible in regard to stripping temperature and flow-rate of the purging gas. This modification, designated the straight and open system, allowed the stripping technique to be utilized without sacrificing sensitivity or capacity, but a few blank peaks in the subsequent high resolution gas chromatogram. A case study of trace organics in the Motala River [Sweden] was presented. This river was a raw water source for water works and was a recipient for industrial and sewage plants.
