摘要

选择了一种由天然材料（苔藓）制成的吸附剂来吸附水表面的柴油。对吸附剂进行了改性，以提高其疏水-亲油特性。从苔藓中选择典型的天然有机吸附剂，并以三种不同的方式进行改性：热水处理（80°C和100°C）、丝光处理和油-水涂层（10%和50%）。进行了水、柴油吸附能力和保油试验。试验表明，热水和碱的简单处理可以改变表面性质，提高吸附能力。80°C热水改性提高了吸附剂的吸油能力，效果最好，但同时也容易增加亲水性。这种吸附剂处理方法不能应用于吸附剂用于清洁水面漏油的情况。同时，在对土壤和其他固体表面进行清洁操作的情况下，将获得更好的吸附结果。

MODIFICATION OF NATURAL OIL SORBENT FOR IMPROVEMENT OF HYDROPHOBICITY

A sorbent made of natural materials (moss) was selected for the sorption of diesel from the surface of the water. The sorbent was modified to increase its hydrophobic–oleophilic characteristics. Typical natural organic sorbent from moss was selected and modified in three different ways: processed with hot water (80 °C and 100 °C), mercerized and coated with oil–water (10% and 50%). Water, diesel sorption capacity, and oil retention tests were performed. Tests showed that simple treatment with hot water and alkali can change surface properties and improve sorption capacity. Modification with hot water at 80 °C enhanced sorbents’ oil sorption capacity and showed the best results but meanwhile, this method readily increased hydrophilicity. This method of sorbent treatment could not be applied in cases where sorbents are used to clean oil spills from water surfaces. Meanwhile, better sorption results would be obtained in cases where cleaning operations take place on soil and other solid surfaces.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
