The invention relates to the technical field of detergent detection, and discloses a synthetic detergent production detection device which comprises a product conveying line and a detection table, the detection table is located on the left side of the product conveying line, an annular feeding piece is arranged at the top of the detection table, and a sample cup is placed at the top in the annular feeding piece; a driving shaft is rotatably connected to the detection table, a raised line I is fixedly mounted on the circumferential surface of the driving shaft, a shaft sleeve is slidably connected to the driving shaft and the raised line I, and a piston sampling piece is arranged between the top of the driving shaft and the top of the shaft sleeve; and a viscosity detection piece is arranged on the rear side of the top of the detection table. When the piston barrel deflects to the position over the product conveying line, the output end of the second air cylinder shrinks, so that the interior of the piston barrel is in a negative pressure state, and the detergent enters the piston barrel; after the piston barrel moves to the position over the sample cup, the output end of the second air cylinder extends, and the detergent in the piston barrel is extruded into the sample cup; therefore, the purpose of automatic sampling is achieved.

According to a natural detergent composition, a detergent composition according to one aspect does not use synthetic chemical components such as metal ion chelating agents, unlike conventional synthetic detergents, so it does not cause environmental pollution, is harmless to the human body, is non-irritating to the skin, has low mineral salt precipitation, and has excellent cleaning power.

The invention relates to a rapid detection method and kit for an anionic synthetic detergent in tableware, and the detection method comprises the following steps: washing the tableware with pure water, and collecting a washing solution; taking the washing liquid, sequentially adding a methyl violet solution and ethyl acetate into the washing liquid, uniformly shaking, and standing for a period of time; and sucking supernatant liquid, comparing the supernatant liquid with a standard colorimetric card in color, and calculating the concentration of the anionic synthetic detergent in the washing liquid according to the color gradation of the standard colorimetric card. The detection method provided by the invention has the advantages of simple pretreatment operation and convenient detection, and is suitable for rapid detection requirements; and 2) the lowest detection mass concentration of the detection method provided by the invention is 0.04 mg / L, which is lower than 0.05 mg / L required by the limit of GB 14934-2016, and the detection method has higher sensitivity and can completely meet the requirement of limit supervision on the anion synthetic detergent.

The invention relates to non-ferrous metallurgy and can be used for producing a saleable product from the waste formed during the wet scrubbing of exhaust gases from aluminium potrooms to remove residual hydrogen fluoride and sulphur dioxide. The invention makes it possible to use spent aluminium electrolysis cell scrubbing solutions (including solutions that have been defluorinated by the extraction of secondary cryolite) to produce a sodium sulphate mixture having a high whiteness index and a low yellowness index, i.e. a competitively priced product suitable for producing synthetic detergents. A spent sodium sulphate solution is first clarified using a synthetic flocculant to reduce suspended fluorides and scrubbing sludge. Filtration of the sodium sulphate mixture slurry is carried out conjointly with washing using cold process water, and the dried sodium sulphate mixture residue is ground to a fineness of minus 200 μm to increase the whiteness index.
