ABSTRACT:
Ionic cellulose-containing substrates reacted with a fatty quaternary ammonium salt such as hexadecyltrimethylammonium bromide have the proper balance of hydrophilic and hydrophobic properties to absorb oil from oil-containing emulsions. Suitable ionic cellulose-containing substrates include agricultural residues, wood dust, acid-derivatized cellulose, and cellulose graft copolymers. These products are useful for cleaning up oil spills and for removing entrained oil from waste water.
