Modified bagasse sheet with functionalized silanes for removing of engine oil

Abstract

SURFACE modification of bagasse paper sheet was carried out using silane derivatives, n-octyl triethoxysilane or perfluoro octyltriethoxy silane, in an ethanol/water medium. The change of sheet surface properties after modification was ascertained by contact angle measurements, scanning electron microscopy and FUR. The capability of the treated bagasse sheet to absorb engine oil from aqueous solution was studied. It was found that the treated sheet was significantly more hydrophobic than the untreated sheet. Treated sheet had little affinity for water and good affinity for oil.
