| Abstract: | Adsorption isotherm of 7 hydrous metal oxides which were prepared by simple alkali precipitation method was discussed systematically and results showed that hydrous metal oxides of Al,Fe,Ni,Cu and Ce fit best with Langmuir linear adsorption equation,and hydrous zinc oxides and hydrous cobalt oxides with linear isotherm in the tested concentration range at 25 ℃.Adsorption data of all 7 hydrous metal oxides can be fit well with Freundlich isotherm.Phosphate adsorption capacity is not proportional to specific surface area among these oxide adsorbents.IR band changes before and after adsorption happen mainly in the range of 800~1 250 cm-1.The experiments prove that the hydrous metal oxides have potential to use as adsorbents for water treatment. |
| Keywords: | hydrous metal oxides adsorption isotherm specific surface area IR spectroscopy |
