[Simulation study on behaviors of sediment phosphorus affected by iron ion].
A simulation study has been done that vertical transport of conduct of phosphorus in sediment affected by iron inorganic salt. The results showed: when 10 mL or 50 mL of 1 mol/L FeCl3 solution were added to the simulation system respectively, phosphorus content in sediments was reduced, however, 30 mL of 1 mol/L FeCl3 solution was added, phosphorus content of sediments increased. Appropriate quantum iron inorganic salt will prevent phosphorus in sediment released to the water, otherwise, iron ion quantum added is too high or too low, to a certain extent, will promote the release of phosphorus in the sediments. The results of the study will help further study on the release of the source of phosphorus and lake eutrophication.
