A Modified Porous Sponge with Selective Ability for Oil Removal from Oil-Water Mixtures

Table 1

Selectivity of the modified sponges.

Oil-water mixture	Selectivity (%)
	5% oil content	25% oil content	50% oil content
Xylene-water mixture	99.8	99.4	99.5
Hexane-water mixture	99.7	99.9	99.6
Dichloroethane-water mixture	99.0	99.8	99.3
Toluene-water mixture	99.1	99.5	99.7
Gasoline-water mixture	99.5	99.7	99.7
Olive oil-water mixture	99.7	99.2	99.4

Selectivity was calculated using the following equation:.
