Method for rapidly detecting benzene compounds adsorption performance by charcoal solution

Abstract

The invention discloses a method for rapidly detecting benzene compounds adsorption performance by a bio-carbon solution. The method comprises the following steps: 1) taking the bio-carbon solution after saturated adsorption of the benzene compounds; 2) filtering the bio-carbon solution obtained in the step 1) to obtain the moisture bio-carbon, weighing the bio-carbon and recording the bio-carbon,and recording the moisture content; 3) employing carbon disulfide for extracting and filtering the bio-carbon obtained in the step 2); and 4) performing gas chromatograph on a carbon disulfide extract obtained in the step 3) and substituting the results into a benzene compounds standard curve, and calculating the concentration of benzene, toluene, p-m-xylene, and o-xylene absorbed in the dried bio-carbon. The method is suitable for detecting the benzene compounds in adsorption liquid of the bio-carbon solution, pre-processing is not required, one-time sampling realizes multi-time determination and analysis, a carbon disulfide desorption direct sample introduction method is employed, under prerequisite that a detection safety factor is ensured, detection time is shortened, detection cost is reduced, and the data analysis is accurate.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to a rapid detection method for the adsorption performance of benzene series by a biochar solution. Background technique [0002] The treatment of benzene series in wastewater by biological activated carbon adsorption is a new technology for controlling pollutants in wastewater. For a large number of benzene series in wastewater, adding biochar can effectively remove benzene series in wastewater, and can be reused repeatedly to achieve the purpose of reducing costs and quickly removing benzene series. [0003] Activated carbon is an effective method to remove organic matter in wastewater. Its disadvantage is that once the adsorption is saturated, it needs to be effectively regenerated. Bio-activated carbon can solve this problem. Adhering effective microorganisms on the surface of activated carbon can effectively regenerate activated carbon after the adsorption of activated carbon...

Problems solved by technology

[0003] Activated carbon is an effective method to remove organic matter in wastewater. Its disadvantage is that it needs to be effectively regenerated once the adsorption is saturated. Bio-activated carbon can solve this problem.

At present, there is no mature method for the detection of benzene series in biochar solution, and there are many deficiencies that need to be improved.
