摘要
Abstract
The content of chlorophyll a is an important basis for evaluating the level of eutrophication in water bodies,and excessive nutrient degree of water bodies will affect the survival and reproduction of aquatic organisms,resulting in disturbance of aquatic ecosystems and destruction of biodiversity.Chlorophyll a is the type of chlorophyll found in almost all types of phytoplankton.Therefore,chlorophyll a content is not only the criterion of water eutrophication,but also an important inference basis for the existing stock of phytoplankton.Water eutrophication is the main problem faced by China's current water environment.In order to elaborate on the rapidity and accuracy of spectrophotometric determination of chlorophyll a content in water,a grinder is used instead of manual grinding for sample preparation,and standard materials are used for standard addition determination.The results show that the detection value of chlorophyll a meets the requirements of standards.关键词
