The invention discloses a total phosphorus real-time online detection chip based on a photo-thermal material, relates to a total phosphorus detection technology, and aims to solve the problems that the digestion time is too long, a required sample amount is too high and a detection device is not easy to carry in traditional total phosphorus detection. The chip is suitable for detecting the total phosphorus content in a water body in real time. The chip comprises a microfluidic chip main body, a digestion plate reaction cabin which is used for digesting a total phosphorus sample water sample, a color developing mixing channel which is connected with the digestion plate reaction cabin and is used for fully mixing and reacting a color developing agent and a sample to be detected, and a detection channel which is used for receiving the finally reacted solution and further detecting the solution through the light source input by the optical fiber, wherein a photo-thermal material carbon film covers a glass substrate area under the reaction cabin.
Description
technical field [0001] The invention relates to optical fluidic chip technology, in particular to a microfluidic integrated chip applied to real-time detection of total phosphorus content in water bodies and a real-time detection method based on the chip. Background technique [0002] Microfluidic chips are emerging research technologies for manipulating liquids at the micron or even nanoscale. Micro-channels with various functions are integrated in the chip, each of which forms a different functional unit area, forming a small laboratory with a clear division of labor. Optical fiber sensors have been greatly studied in biomedical measurement and environmental protection due to their outstanding advantages such as corrosion resistance, anti-electromagnetic interference, high precision, and compact structure. Optical fiber absorbance detection based on Beer Lambert's law, combined with micro-scale channels, can achieve detection with high precision and sensitivity. Its appl...
