Abstract

With the open modification of the system for closed-loop stripping analysis, the stripping conditions can be varied widely. By using stripping temperatures between 30 and 90°C, the technique can be optimized to meet specific analytical demands. In particular, the analysis of trace organics in water can be extended to less volatile and more polar compounds. Desorption of the adsorbent is often the key step in the stripping procedure. Efficiency of extraction from the filter is generally low. This has been investigated, and a solvent mixture not used previously for stripping analysis (carbon disulphide—benzene—methanol, 65:30:5) is recommended.
