Abstract

The invention discloses a device and a method for detecting chlorophyll a in a water body. The device consists of a housing, a microfluidic chip, a micropump, a water storage tank, a light source, a two-in-one optical fiber, a detection and display module, and a lithium battery. The water sample is pumped into the microfluidic chip through the micropump, and the light source of 650nm and 940nm is sequentially irradiated on the detection area of ​​the chip, and the transmitted light signal is received by the detection and display module in sequence, and the content of chlorophyll a in the water body is obtained through signal processing and output to the display. The invention is simple in operation, portable and cheap, improves the automation degree of detection, and can be applied to rapid, automatic and on-site detection in eutrophic water areas.

Description

technical field [0001] The invention relates to microfluidic technology and photoelectric detection technology, in particular to a detection device and method for chlorophyll a in water bodies. Background technique [0002] A large amount of chlorophyll a exists in small plankton such as cyanobacteria, green algae and diatoms in the water body. By measuring the content of chlorophyll a in the water body, the growth status of the algae can be predicted, so as to judge the degree of eutrophication of the water body, so as to take Take appropriate measures to prevent algal blooms. [0003] Most of the traditional portable chlorophyll detectors are clamp-type detection, and the chlorophyll information is obtained by clamping the leaves with a fixture. Such devices cannot detect liquids, and algae plankton are 50 microns to 1 mm in size, which is too small for traditional detection devices to detect. [0004] In addition, existing technologies typically sample water quality and...
