  • In this study, the phosphate adsorption characteristics of zirconium mesostructures synthesized under different conditions were estimated. X-ray diffraction analysis, phosphate adsorption isotherm test and kinetic test was performed for the zirconium mesostructures synthesized at different inorganic/surfactant molar ratio and with different surfactant templates. The test results were analyzed with adsorption models. From this work, it was found that at the inorganic/surfactant molar ratio of 1/0.50($0.013{\cdot}Zr(SO_4){_2}:0.068{\cdot}surfactant:5.55{\cdot}H_2O$), the meso-pores in the material could be most uniformly and clearly formed and thus the adsorption capacity and reaction rate of material could be maximized. And the pore size in the mesostructure increased with the chain length of surfactant template used, and maximum phosphate adsorption amount and reaction rate could be achieved with the zirconium mesostructure synthesized with the surfactant template of dodecyltrimethylammonium bromide.
