The upper layer of water samples that do not contain settleable solids should be transferred into sample bottles for analysis. When collecting total phosphorus items in surface water, when the turbidity of the raw water is between 200NTU and 500NTU, it is necessary to let it stand for 60 minutes and then transfer the upper layer of water samples into sample bottles for analysis.
