Method Name:
Sample Reconstitution. Official Name: Sample Reconstitution

The samples, as received, contain paper pulp, and are 2% in concentrated hydrochloric acid or nitric acid. Samples containing hydrochloric acid also might contain a holding reductant if nuclides of iodine are of interest. The paper pulp and other particulate material are filtered, wet ashed in a Teflon beaker with nitric and perchloric acids, and the solution is evaporated to fumes of perchloric acid. The hydrochloric and hydrofluoric acid wash of the container is added to this perchloric acid fraction and the solution is evaporated until a milliliter of perchloric acid remains. The perchloric acid solution is mixed with the original filtrate and transferred back into the original container, thus providing a stable, homogeneous sample.

This procedure is applicable to the recovery and dissolution of the insoluble fractions present in liquid samples from nuclear power facilities and to which acid and paper pulp were added at the time of collection. This procedure normally is not used with environmental water samples
