摘要：
A novel adsorbent of flower-like magnesium oxide has been prepared via hydrothermal method using CTAB as a structure director. Experiment results showed that the precursor of flower-like MgO is basic magnesium carbonate, and MgO with large surface area was obtained after calcination at 600 degrees C. The adsorption performance of flower-like MgO was also studied in lead solution. The results of adsorption are conformed to Langmuir model, and maximum adsorption is 320 mg.g(-1), which means the novel flower-like MgO has a high adsorption performance.
