Device for extracting pyritic sulfur contained in geological sample

Abstract

The invention provides a device for extracting pyritic sulfur contained in a geological sample. The device comprises a nitrogen gas path unit, a CrCl2 gas preparation unit, a sample reaction unit and a gas absorption unit, wherein a reaction vessel inside the sample reaction unit is arranged on a heating type magnetic stirrer, and the reaction vessel is provided with a liquid inlet, a gas inlet and a gas outlet; a condensation pipe inner pipe is arranged above the gas outlet through a porous glass stopper, a condensation pipe outer pipe is wound outside the condensation pipe inner pipe; a separating funnel B and a separating funnel A are respectively communicated with the reaction vessel through sampling pipes which correspond to the separating funnel B and the separating funnel A and a sampling port; the sampling pipes are both inserted into the sampling port; a nitrogen cylinder inside the nitrogen gas path unit is communicated with the reaction vessel through a vent pipe and the gas inlet and communicated with the separating funnel B after being connected with the upper part of the separating funnel B through a two-port type gas-distributing pipe; and the gas absorption unit comprises a round-bottomed flask, a surge flask, a gas absorption test tube and a tail gas absorption bottle which are sequentially communicated through a pipeline. The device provided by the invention can effectively extract the pyritic sulfur contained in the geological sample and has the characteristics of economy, easiness, convenience and environmental friendliness.

Description

technical field [0001] The invention relates to a device for extracting pyrite sulfur in geological samples, which is used as an analysis instrument for pyrite sulfur isotopes, and is mainly used in the fields of paleoenvironment and paleocean research. technical background [0002] In paleoenvironmental and paleocean research, pyrite sulfur isotope analysis and pyrite quantitative research in geological samples are required, but there is no effective method and instrument in this regard in the existing technology to meet the requirements of geological samples. The iron ore is exclusively extracted online, and at the same time it can meet the requirements of environmental friendliness. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a device for extracting pyrite sulfur in geological samples, which can not only realize quantitative and effective extraction of pyrite sulfur in geological samples, but also does n...
