To fabricate oil/water separating material with good selective absorption capacity
natural materials including cotton and calcium carbonate (CaCO
3
)were selected. Cotton fibers/CaCO
3
composites were prepared by a biomimetic mineralization approach
through which CaCO
3
particles were uniformly coated on the surface of cotton fibers by an alternative soaking process (ASP). Polyacrylic acid (PAA) was first introduced onto the surface of the cotton before CaCO
3
mineralization to avoid the agglomeration of the formed inorganic particles. The prepared cotton fibers/CaCO
3
composites were further modified by sodium stearate
which is a cost-efficient hydrophobic agent commonly used to modify CaCO
3
. By this way
the water contact angle of the composites increased to 145°
as compared with the water contact angle (0°) of the pristine cotton
illustrating that the surface wettability of the cotton fibers was changed successfully from hydrophilic to hydrophobic. FTIR results demonstrated that the hydrogen bonds existed between CaCO
3
and cotton fibers
which provided the binding force for the composites. A series of samples with different concentrations of CaCO
3
were prepared
and the relationship between the wetting behavior and the concentration of modified CaCO
3
were investigatged and discussed in detail. In addition
the selective absorbing capability against oil/water mixture was measured for the composite. The resultant hydrophobic cotton fibers showed good selective absorption to different oils
including vegetable oil
crude oil
paraffin oil
simethicone and chloroform
from the oil/water mixtures. The absorption capacity achieved was as high as (17.4 ±1.16)
(23.6 ±1.9)
(20.5 ±1.5)
(22.7 ±1.2) and (27.3 ±1.0) g/g for different oils. In particular
the adsorption rates of simethicone and chloroform were maintained higher than 80% even after 30 cycles of readsorptions
indicating the good reusability of the composite fibers. All these results demonstrated that the novel hydrophobic cotton fiber/calcium carbonate composites had potential applications in the treatment of oil-water pollutants.
