Abstract

The invention discloses an on-line enrichment system of organic pollutants in a water body. The on-line enrichment system is characterized by comprising an acquisition device (1) which is communicated with an enrichment device (2); the enrichment device (2) is connected with an elution device (36); and the outlet end of the enrichment device (2) is connected with an inlet of an on-line concentration device (3) which is communicated with an automatic sample introduction device (4). The on-line enrichment system of the organic pollutants in the water body has skillful structure and convenient operation, can realize the modularly and automatic detection, organically integrate various steps for detecting the organic pollutants in the water body into a whole and can save a large amount of timeand labor.

Description

technical field

[0001] The invention relates to an online enrichment system for organic pollutants in water, which can perform steps such as sampling, enrichment, elution, online concentration, and automatic sampling. Background technique

[0002] Ultra-trace organic pollutants existing in seawater, such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs), etc., although their content is very low, they have been in this state for a long time There is a toxic effect on organisms in this environment, and this toxic effect may also be amplified through the food chain, so it is necessary to monitor the content of organic pollutants in the water at any time. Now, when it is necessary to monitor the seawater to be measured, manual sampling is required, and then the sample water body is enriched through the enrichment device, and after enrichment, the elution process is performed. After the eluted water body is taken out...
