Description
Technical field
The present invention relates to resolutions to test, and in particular to a kind of component extracted for Specimen eliminating.
Background technique
Existing Specimen eliminating extraction is mainly used for metal ion measurement, and principle is that sample is cleared up through nitric acid, perchloric acid
Afterwards, ammonium pyrrolidine dithiocarbamate (APDC) is added in subacidity sample liquid and metal ion forms complex compound, it is accurate to add
Enter methyl iso-butyl ketone (MIBK) (MIBK) quantitatively to extract, extracting solution is for Flame Atomic Absorption, and steps are as follows:
1, a certain amount of sample is accurately weighed to be put into beaker；
2, the mixing digestion solution of nitric acid, perchloric acid is added in beaker, then the cap upper surface ware on beaker；
3, beaker is heated, until the solution clarification in beaker；
4, the solution in cooling beaker, then plus water rinses bottle wall on a small quantity and surface plate, the liquid of flushing also enter in beaker；
5, it heats in beaker to beaker again and emits white cigarette, cool down again；
6, it is diluted with water solution into beaker, and bromophenol blue indicator is added；It is proper with 40% sodium hydroxide and 5% nitric acid adjustment solution
It is well in yellow.
7, it transfers the solution into volumetric flask；
8,2% APDC solution 2.5ml is added into solution；
9, solution is diluted with water into volumetric flask, until solution is at the 2/3 of volumetric flask volume；
10, MIBK solution 10ml is accurately added, closes volumetric flask with bottle stopper, then acutely shaking 200 times；
11, add water into volumetric flask, until solution reaches volumetric flask bottleneck；
12,1h is placed, keeps lower leaf on organic solution and aqueous solution clear；
13, lid 8 is pulled up by force ring 10 from extraction flask, bottleneck organic extract will be floated on and sucked with capillary burette
Funnel and filter equipped with anhydrous sodium sulfate filter paper enter in test tube, for Flame Atomic Absorption.
It can be seen that from above-mentioned steps, which not only needs to shift solution between beaker and volumetric flask, also needs to erect
Alcolhol burner and other auxiliary facilities heat beaker, complex steps, and test efficiency is low.
