| Abstract: | Zn-Al houghite with different urea concentrations has been prepared by hydrothermal method.The samples of calcined houghite obtained after calcination are characterized by methods,such as X-ray diffraction (XRD),field-emission scanning electron microscopy(FE-SEM),nitrogen adsorption-desorption isotherms(BET), fourier transform infrared(FTIR),etc.The adsorption capacity of phosphate in water by houghite and its calcined products has been investigated.The results show that the adsorption of phosphate in water... |
