| 英文摘要 | A quantitative analytical method of Keggin polycation [(AlO4Al12(OH)(24)H2O)(12)](7+) (Al-13) and [(AlO4)(2)Al-28(OH)(56)(H2O)(26)](18+)(A(30)) in hydrolytic polymeric aluminum (HPA) aqueous solution was developed, and the species distribution of eight HPAs with total aluminum concentrations (Al-T) between 0.1 and 2.0 mol/L were studied quantitatively using high field Al-27 nuclear magnetic resonance (NMR) under 70 degrees C. The concentrations of Al-13 and Al-30 can be measured accurately by this method. The linewidth of Al-30 are very sensitive to temperature and become narrower on heating or measured on high field NMR spectrometer, and the resolution will be improved. AlT is a dominant factor of influencing the aluminum species distribution in high concentrated HPA(Al-T >= 0.5 mol/L). The concentration of Al-13 increases with the increasing of Al-T while Al-T <= 0.5 mol/L, and decreases with the increasing of Al-T while Al-T >= 0.5 mol/L. The concentration of Al-30 increases with the increasing of Al-T, and it is greater than the concentration of Al-13 while Al-T >= 0.5 mol/L. Al-30 becomes one of dominant polymeric aluminum species while the Al-T >= 0.5 mol/L. |
