Analysis on Impact on Determination Results of Total Phosphorus by Sedimentation Time of the Sediments in River during High Water Period

The phosphorus content is an important indicator of water quality.The main sources of total phosphorus in the rainy period come from the sediments in the adsorption of organic phosphorus and inorganic phosphorus.A trend of decreasing phosphorus content with longer sedimentation time is revealed.So the main factor of influencing the determination results is focused on the sedimentation time of the sediments of the samples in the lab.
