Method for detecting drainage oil

Abstract

The invention discloses a method for detecting drainage oil. The method is characterized by comprising the steps as follows: a to-be-detected oil liquid is added into a specific solution; the to-be-detected oil liquid is decomposed into uniformly distributed molecular particles in the solution after the mixture is uniformly rocked and vibrated; then an optical device capable of detecting the particle diameter of each molecular particle in the solution is adopted to detect the solution, so that a particle diameter distribution diagram of the molecular particles formed by the to-be-detected oil liquid in the specific solution is obtained; and the particle diameter distribution diagram is compared with a sample particle diameter distribution diagram obtained through a standard sample in advance, and then whether the to-be-detected oil liquid belongs to the drainage oil can be judged. Compared with the prior art, the method can be used for judging and detecting the drainage oil, and has the advantages of high judgment accuracy, convenience in operation, simplicity and practicability, and the purpose of simply and conveniently detecting the drainage oil or waste cooking oil is achieved.

Description

technical field [0001] The invention relates to a method for detecting waste oil by adopting light scattering technology, in particular to a method for distinguishing normal edible oil and waste oil / soil oil. [0002] Background technique [0003] Gutter oil generally refers to all non-edible low-quality oils and fats. Gutter oil contains a lot of harmful substances, such as heavy metals, nitrite, benzopyrene, aflatoxin, trans fatty acids, etc. Long-term intake of waste oil will cause great harm to the human body, such as diarrhea, enteritis, insomnia, dysplasia, accompanied by heart, liver and other lesions, and even induce cancer. [0004] At present, waste oil has been used to produce fuel, plastic additives, rubber and other industrial products in developed countries such as Britain and the United States; in China, due to the limitation of management system and development technology, waste oil has returned to the dining table in large numbers under the use of criminals...

AI Technical Summary

Problems solved by technology

However, the applicant's specific experimental research found that since waste oil only contains a very small amount of impurities, most of them are oils with the same properties as edible oils, and impurities often have the characteristics of colorless and transparent, so when using this method to judge , in fact, it is difficult to reflect the difference, and it is difficult to improve the accuracy of judgment
