摘要：In this study, selective removal behavior of phosphorus from seawater using mechanochemical treated zircon sand was investigated.The product showed the same adsorption amount in seawater as that in the aqueous solution at pH 7, which means that phosphorus can be selectively adsorbed on the product in the solution with high salt concentration.The adsorption isotherm in seawater was found to applicable to Langmuir model rather than Freundlich model, and the calculated maximum adsorption amount was 0.01 mmol g -1 .The adsorption kinetics of the phosphorus in seawater fit much better to pseudo-second-order model than to pseudo-first-order model.Phosphorus can be recovered from deep seawater using the column.Chloride and sulfate are not affected to phosphorus removal, while carbonate ion affects on phosphorus removal of mechanochemical treated zircon sand.
