Abstract

Described herein are absorbent compositions and methods of making and using the compositions. The absorbent composition including a hydrophilic cellulosic material functionalized with one or more hydrophobic chemical modification agents. The one or more hydrophobic chemical modification agents can be polymerized with or grafted to the hydrophilic cellulosic material via a chemical, physical or ionic bonds. The hydrophilic cellulosic material can exhibit an increased level of hornification. The method of making the absorbent composition including: a) contacting a hydrophilic cellulosic material with one or more hydrophobic chemical modification agents to form a precursor mixture; and b) allowing the one or more hydrophobic chemical modification agents to react with the hydrophilic cellulosic material to form an absorbent composition. The absorbent composition may be used for selective oil absorption and/or chloroform absorption. For example, the compositions may be used for oil spills, leaks, or discharges cleanup and remediation.
