Description
Technical field
The present invention relates to a kind of chromatograph assay method of material, belong to particularly a kind of method of measuring anthracene content in coking industry carbolineum by micellar electrokinetic capillary chromatography.
Background technology
What in industry standard YB/T 5086-2005 < < industry anthracene, in anthracene content assaying method > >, measure that in industrial anthracene, anthracene content adopts is chemical method.The analysis principle of the method is: anthracene is as conjugated diolefine, in organic solvent chlorobenzene, play addition reaction (9 with maleic anhydride, 10 there is Diels-Alder reaction), need add hot reflux 20 ~ 30 minutes, the cooling rear acid generating with the maleic anhydride hydrolysis of standard solution of sodium hydroxide titration surplus, then be converted into anthracene content according to standard solution of sodium hydroxide consumption.The method analysis time long (nearly 1 hour), the large and complex steps of personal error, adopts chlorobenzene (toxicity is larger) to make solvent environment and operating personnel healthy is all produced to harmful effect.
Due to features such as chromatography have good separating effect, analysis speed is fast, detection sensitivity is high, applied widely and easy and simple to handle, in production, scientific research, teaching, food, environmental protection, universe exploration etc. are multi-field, be used widely.Capillary column claims again open hole capillary column or open-tubular capillary column, internal diameter mostly is 0.1～0.5mm, fixing phase portion and interposition is hollow in the inner, so chromatographic column perviousness is large, resistance to mass tranfer is little, has better separation efficiency, analysis speed faster than packed column.The theoretical cam curve of every meter of column length of conventional packed column is 102～103, capillary column is 103～104, post effect is slightly better than conventional packed column, but the column length of capillary column mostly is the more than 10 times of conventional packed column, total post effect is more much higher than conventional packed column, therefore when Analysis of Complex sample, can show its characteristic.
At present, employing is that chemical method is measured the anthracene content in industrial anthracene.Because adopting chlorobenzene, chemical method makes solvent and maleic acid anhydride reactant, with NaOH titration, anthracene content in industrial anthracene is carried out to quantitative test, toxicity is larger, easily operator's physical and mental health is damaged, and operating process is loaded down with trivial details, analysis time is long, and the general used time is at 40 ~ 50 minutes, and has the artificial drawbacks such as systematic error.
Before the present invention, do not adopt chromatography determination coking industry complex sample, because the pre-service of sample is more difficult, because anthracene in industrial anthracene, phenanthrene, carbazole, firefly anthracene, pyrene, the material such as to bend be the condensed-nuclei aromatics at three rings or Fourth Ring, under general solvent normal temperature, normal means are difficult to it to dissolve completely, therefore cannot carry out stratographic analysis.
