　　Na4EDTA and EDTA were adopted as new additives to intensify the seeded precipitation process of sodium aluminate solution.The effects of the two additives at certain concentrations on the seeded precipitation ratios of sodium aluminate solutions,particle size distribution (PSD) and morphology of precipitated gibbsite were investigated using titration method, particle size analyzer and scanning electron microscope (SEM),respectively.
