Abstract
Apparatus for eliminating halide ions such as chloride ions from aqueous solutions having a hollow cylindrical sample holding chamber ( ), the front end of which has an orifice ( ) and in the vicinity of which is disposed a filter plate ( ) that extends over the cross section of the sample holding chamber ( ) and is liquid-permeable and essentially impermeable for solids and is inserted in a fixed manner into the hollow cylinder; a plunger ( ) which can move to and fro in the sample holding chamber ( ) and has a plunger stem ( ) attached thereto engages in the open rear end ( ) of the sample holding chamber, and, in the sample holding chamber ( ) between the filter plate ( ) and the plunger ( ) is disposed a freely movable bed ( ) of an adsorbent reacting with halide ions and forming a sparingly soluble compound, which bed fills a part of the sample holding chamber ( ). The adsorbent is preferably charged with silver nitrate as compound reactive with halide ions.
