specific Embodiment approach 1

[0014] Specific embodiment 1: The emulsion pretreatment clarifier in this specific embodiment includes short-chain aliphatic ketones, non-ionic detergents, aqueous surfactants and strong bases; wherein the mass concentration of the aqueous surfactants is 1% ; Short-chain aliphatic ketones account for 20%-50% of the total volume of the emulsion pretreatment clarifier, non-ionic detergents account for 20%-50% of the total volume of the emulsion pretreatment clarifier, aqueous surfactant solution It accounts for 5%-30% of the total volume of the emulsion pretreatment clarifier, and the concentration of the strong base in the emulsion pretreatment clarifier is 0.02~0.06mol / L.

specific Embodiment approach 2

[0015] Specific embodiment two: this embodiment is different from specific embodiment one in that both the short-chain aliphatic ketone and the non-ionic detergent are of analytical grade. Others are the same as the first embodiment.

specific Embodiment approach 3

[0016] Specific embodiment three: This embodiment is different from specific embodiment one in that the short-chain aliphatic ketone is methyl ethyl ketone. Others are the same as the first embodiment.

Abstract

A pretreatment clarifier of an emulsion and a preparation method thereof relates to a clarifier and a preparation method thereof. In order to solve the problems of long settling time, complex operation and not ideal settling effect because no special clarifier is used when the spectrophotometry is used for analyzing the emulsion. The invention discloses the pretreatment clarifier of the emulsion and the preparation method thereof. The volume of the pretreatment clarifier of the emulsion is taken as an overall volume, and an aqueous surfactant solution accounting for 5 percent to 30 percent ofthe overall volume and 1 percent of the mass concentration is mixed with alkali to form an A solution. Short chain aliphatic ketone accounting for 20 percent to 50 percent of the overall volume is mixed with a non-ionic detergent accounting for 20 percent to 50 percent to form a B solution. The A solution is mixed with the B solution to form the pretreatment clarifier of the emulsion. The alkali concentration of the pretreatment clarifier of the emulsion is 0.02-0.06mol / L. The invention can be widely used for the analysis and the pretreatment of dairy products, starters, oil-water emulsions or part cosmetics.

Description

technical field [0001] The invention relates to a clarifier and a preparation method thereof, in particular to a clarifier used for emulsion pretreatment and a preparation method thereof. Background technique [0002] Due to its simple method, stable performance and small error, spectrophotometry is widely used in the analysis and detection of substances. However, because the emulsion is naturally milky white and light cannot be transmitted, it cannot be directly analyzed and detected by spectrophotometry, and the emulsion needs to be clarified and pretreated. At present, there is no clarifier specifically for the clarification and pretreatment of emulsion photometry. Emulsion clarification pretreatment methods mainly include centrifugation, acid precipitation and so on. Centrifugal separation and acid precipitation have disadvantages such as long clarification time, cumbersome operation, and unsatisfactory results. For example, centrifugal separation uses a high-speed ce...
