摘要
通过浸渍———干燥———焙烧法制备预载镧氧化物稀土吸附剂,探讨了该吸附剂对水中磷的吸附性能。研究表明在镧离子浓度为0 025mol/l、pH为10-11的溶液中浸渍,于500℃温度下焙烧制得的稀土吸附剂,其除磷效果可达95%。
The process of infusion, drying and calcinations makes lanthanon oxide as rare earth absorbent. The article studies the absorption effects of this kind of rare earth absorbent to phosphorus in water. Research shows that the effects of dephosphorization can reach 95% under the following conditions: 0.025mol/l of concentration of lanthanon iron, 10 to 11 of pH, and calcinations at the temperature of 500 degree.
