Abstract

The invention relates to a preparation method for an algae solution used for determining the chlorophyll content through a fluorescence method. The preparation method includes the steps that a chlorella pyrenoidosa species is selected, a BG-11 culture medium is prepared, sterilized, cooled and inoculated with the algae species under the aseptic condition, after inoculation is completed, the culture medium is placed in a constant-temperature illumination incubator to culture the algae species, and before the culture medium is sterilized, agar powder is added into the BG-11 culture medium to culture chlorella pyrenoidosa. According to the gelling property and stability of the agar powder, the preparation method for the algae solution is provided, the agar powder (0.08-0.10 g/100ml) is added into the BG-11 culture medium to culture the chlorella pyrenoidosa as a suspending agent, the cultured chlorella pyrenoidosa is used for preparing the algae solution, the suspension property and stability of the algae solution are improved, and then the result accuracy of determining the chlorophyll content through the fluorescence method is ensured.

Description

technical field [0001] The invention belongs to the technical field of water quality environment monitoring, and in particular relates to a method for preparing algae liquid for measuring chlorophyll content by fluorescence method. Background technique [0002] The content of chlorophyll a reflects the quantity of algae and the water quality in the water body to a certain extent. It is a routine monitoring item in the water quality environment monitoring and one of the eutrophication indicators of the water body. [0003] laboratory spectrophotometry [1-2] , fluorescence spectrophotometry [3] It is the most commonly used method for laboratory determination of chlorophyll a to achieve quantitative determination of phytoplankton. Fluorescence photometry is used to measure chlorophyll a in water, and the sensitivity is 10 times higher than that of spectrophotometry. It does not require pretreatment of samples, is simple to operate, and can be continuously monitored. With the ...
