Background technology
There are Predatory relation between planktonic organism, zooplankter to the predation of phytoplankton and particulate matter make this three it
Between there are the differences of trophic level, this species diversity can directly result in detections such as isotope, organic pollution and heavy-metal residuals
In the process, the testing result between phytoplankton, zooplankter and particulate matter will produce larger difference, if isotope is from high nutrition
The fractionation of grade to low nutrition grade makes the nitrogen isotope value of zooplankter be far above phytoplankton and particulate matter, and organic
Object contaminates the bioaccumulation effect because of Different Nutrition grade in detection process, but also the organic pollution content in zooplankter body is remote
Higher than as basic food source phytoplankton and particulate matter.Therefore, to the separation of phytoplankton, zooplankter and particulate matter
It is very necessary.
But the phytoplankton, zooplankter and suspended particulate substance in Large River water body often mix, wherein

The grain size of object and particulate matter is all in similar range（45 μm~1000 μm）, the sample that is acquired with traditional plankton net
Substantially it all mixes, it is difficult to further be detached.
Currently, existing separation phytoplankton, zooplankter, the method for organic particulate matter are sufficiently complex and efficiency is low, example
If external relatively advanced method is divided again with zooplankter after first adsorbing phytoplankton and particulate matter using silica
From in addition to this, also more researcher covers net using multilayer（Different pore size）The mode filtered step by step is to different grains
The planktonic organism of diameter and suspended particulate substance are sieved, the problem of these methods maximum be consumptive material price costly, such as high-purity
Silica adsorbent it is expensive, mostly obtained by the foreign procurement, and although the mode of multilayer set net reduces cost, still
Sample losses amount is big during collection and separation, it is difficult to meet in scientific research the needs of to large sample size.
