Assay method scanning spectra, directly determines the oil content collection of illustrative plates of solvent free extract water sample with fluorescence method under the same conditions, then right
The quasi- oil concentration curve of sighting target, calculates oil content in water outlet；This method cannot be used for the detection of oil content in waste oil containing metallurgical slag,
It is primarily present following method problem：(1) substantial amounts of Solid micro material is contained in Ferrous Metallurgy slag inclusion waste oil, it is impossible to
To accurate fluorescence spectrum；(2) this method needs to prepare, and there is certain gradient oil concentration curve to be to need same type standard substance
Oil, and Ferrous Metallurgy slag inclusion waste oil is difficult to collect same type standard substance oil.The technology is only suitable for on-line checking water petrochina class
The detection of content, is not suitable for oil content detection in slag inclusion waste oil in metallurgical production.Chinese patent application CN201210444737.3,
Entitled waste oil liquid characteristic detection method, discloses a kind of application Infrared Spectrum Technology-multielement analysis quantitative spectrometric and determines
Property research, detection of the comprehensive multi-disciplinary knowledge to waste oils properties judge oil product product by the characteristic of relatively new and old oil product
Qualitative change information technology solution, the technical scheme does not apply to the detection of oil content in slag inclusion waste oil.
Prior art can not accurately be detected to oil content in the waste oil containing metallurgical slag.
The content of the invention
It is an object of the invention to provide a kind of detection method of oil content in waste oil containing metallurgical slag, mainly solve to contain
The technical problem that oil content can not be detected accurately in the waste oil of metallurgical slag.
The technical solution adopted by the present invention is：The detection method of oil content in a kind of waste oil containing metallurgical slag, including with
Lower step：
1) accurately weigh the waste oil sample that 10.00~15.00g contains metallurgical slag to be placed in 250ml separatory funnels, add water

50ml carries out concussion extraction, and upper solution is transferred in beaker A after standing 20~30min, oil is added in lower floor's solution
30~50ml of ether carries out concussion extraction again, stands and upper solution transfer is incorporated into former beaker A again after 20~30min；
2) 10~15g of anhydrous sodium sulfate is added in the solution in beaker A, constant weight beaker B is filled into after being sufficiently stirred for
In, beaker B first is placed in into 40~50min of heating evaporation in 80~90 DEG C of hot baths, to remove most of petroleum ether, then will burn
Cup B is transferred in 70~80 DEG C of baking ovens 10~20min of drying, then beaker B is placed in drier be cooled to it is right after 15~25 DEG C
Beaker B weighs；
3) sample oil content is calculated, sample oil content presses formula C=(m2-m1)/m × 100% is calculated, and in formula, C is sample
Middle oily weight/mass percentage composition, unit is %；m1For the quality of constant weight beaker B, unit is g；m2For the oil after oven for drying
With beaker B quality sum, unit is g；M is the quality of sample, and unit is g.
The inventive method by first being pre-processed to the waste oil containing metallurgical slag after again using petroleum ether extraction separate
Method, realizes the accurate measurement of oil content in the waste oil containing metallurgical slag.
The inventive method is the recycling of the waste oil containing metallurgical slag, and price evaluation provides accurate number in waste oil transaction
According to support.
The present invention has following good effect compared with prior art：1st, the inventive method has filled up the waste oil containing metallurgical slag
The detection technique blank of middle oil content.2nd, the data precision is high, easy to operate, labor intensity is low for the inventive method detection.
