Preparation and Characterization of Impurely Irrigated Soil Adsorbent from Beaches
摘要
Abstract
[ Objective ] We aimed to study the preparation methods of impurely irrigated soil adsorbent from beaches, as well as its ability to absorb phenol. [ Method] Using hydrochloric acid as activator, we compared the influences of various soil adsorbents on the adsorption of phenol through the desired orthogonal tests where the addition of saw dust, concentration of hydrochloric acid, liquid-solid ratio and carbonization temperature varied. Afterwards, we characterized this soil adsorbent. [ Result] For the soil adsorbent made under the optimal conditions, that is, addition of saw dust was 20% , concentration of HC1 was 1 mol/L, the ratio of liquid to solid was 2:1, carbonization temperature was 500 ℃ , and activation time was one hour, the absorption efficiency of phenol in water by the prepared soil adsorbent reached above 90% . Characterization showed that the prepared soil adsorbent changed greatly in the structure, that is, soil pore and carbon content increased obviously, as well as its adsorption efficiency. [Conclusion] The prepared soil adsorbent by this method greatly improved the absorption efficiency of phenol in water, which provided a novel method for the reasonable utilization of saw dust, with good prospects.关键词
