Method for analyzing micro-plastic pollutants in drinking water

Abstract

The invention discloses a method for analyzing micro-plastic pollutants in drinking water, and relates to the technical field of drinking water pollutant analysis. The method comprises detection of micro-plastic pollutants in drinking water, establishment of a micro-plastic extraction and enrichment technology and a detection method in drinking water, and optimization of detection conditions. The detection of the micro-plastic pollutants in the drinking water comprises a dyeing microscopy method and a Fourier transform infrared spectroscopy method. The method for detecting the micro-plastic pollutants in the drinking water comprises the following steps: step 1, taking table salt, tap water, urine and ultrapure water as research objects, purchasing a table salt sample in a supermarket, and selecting three different types of salt, namely Yisuan Tianfuzhen well salt, Caka natural lake salt and Yiyantang natural sunlight sea salt (algae iodine). According to the invnetion, the mature and efficient detection method is established, effective technical support is provided for food and related departments to monitor the quality and safety of commercially available drinking water and other related products, the product quality is improved, and the life health and safety of consumers are protected.

Description

technical field [0001] The invention belongs to the technical field of analysis of drinking water pollutants, in particular to a method for analyzing microplastic pollutants in drinking water. Background technique [0002] The transmission of microplastics through the food chain will eventually affect the health of each of us. It is particularly important to study the source, generation, transmission route, monitoring, and prevention and control measures of microplastics as soon as possible. However, in China, research on microplastics in oceans and rivers is very important. There are many reports, but there are few reports on the analysis methods and pollution status of microplastic pollution in drinking water. Therefore, we have improved this to overcome the lack of analysis methods and pollution status of microplastic pollution in drinking water in China. Reported deficiencies, a method for the analysis of microplastic pollutants in drinking water is proposed. Contents ...
