Device for online detection of atmospheric salt fog content and detection method thereof

A device for online detection of atmospheric salt fog content, comprising a sampling module and an analysis module, wherein

• the sampling module comprises a liquid absorbent storage tank, a liquid reagent storage tank, an air pump, a relay pump, a sampling bottle, a reaction bottle, a sampling syringe, and a cuvette,
• wherein the air pump is configured to draw an atmosphere into the sampling bottle,
• the relay pump is configured to draw a liquid absorbent in the liquid absorbent storage tank into the sampling bottle, draw a solution in the sampling bottle into the reaction bottle, and draw a liquid reagent in the liquid reagent storage tank into the reaction bottle,
• the cuvette is provided on a conveyor,
• the sampling syringe is installed on a movable component, and
• the movable component drives the sampling syringe to move between the reaction bottle and the conveyor, so that the sampling syringe draws and injects all solution in the reaction bottle into the cuvette provided on the conveyor;
• and
• the analysis module comprises a spectrophotometer, the spectrophotometer is configured to detect an absorbance of an injected solution in the cuvette.
