“…Low pH and high ion strength of the liquid phase increased the adsorption of TCS onto activated carbon, kaolinite, and montmorillonite, while the effect of humic acid was found very complex (Behera et al 2010). Thus, sorption can be affected by sediment size fraction, pore volume, and property of aquatic phase.…”

Adsorption and degradation processes of triclosan (TCS) were studied in the laboratory using fieldcollected sediments of different physicochemical properties. Batch equilibrium experiment indicated that adsorption isotherms were fitted well to both linear and Freundlich model with linear sorption coefficients (K d ) varied from 147 to 1,425 mL μg. The sediment with a higher organic carbon content and a lower pH value had the greatest adsorption capability. Degradation experiment showed that triclosan was relatively stable in water with calculated half-life values ranged from 89 to 161 days. No degradation in sterilized water suggested that the loss of triclosan was due to biological processes. Degradation was more rapid in water-sediment system than in water, and the calculated half-life value in watersediment systems ranged from 32 to 62 days. Methylation of triclosan was observed in all studied sediments, but the amount of methyl-triclosan (M-TCS) accounted for less than 5 % of the degradated TCS.

“…Adsorption using activated carbon is ideal for removing small molecular organic compounds due to the availability of high surface area, and combination of welldeveloped pore structure and surface functional group properties (Dąbrowski et al 2005;Li et al 2002). Removal of several pharmaceuticals by activated carbon has been demonstrated (Behera et al 2010;Synder et al 2007;Ternes et al 2002). The removal of ibuprofen from aqueous phase using commercially available activated carbon and activated carbon prepared from wastes such as cork and plastic have been reported in the literature (Melillo et al 2004;Mestre et al 2007Mestre et al , 2009).…”

Pharmaceuticals have gained significant attention in recent years due to the environmental risks posed by their versatile application and occurrence in the natural aquatic environment. The transportation and distribution of pharmaceuticals in the environmental media mainly depends on their sorption behavior in soils, sediment-water systems and waste water treatment plants, which varies widely across pharmaceuticals. Sorption of ibuprofen, a non-steroidal anti-inflammatory drug, onto various soil minerals, viz., kaolinite, montmorillonite, goethite, and activated carbon, as a function of pH (3-11), ionic strength (NaCl concentration: 0.001-0.5 M), and the humic acid concentration (0-1,000 mg/L) was investigated through batch experiments. Experimental results showed that the sorption of ibuprofen onto all sorbents was highest at pH 3, with highest sorption capacity for activated carbon (28.5 mg/g). Among the minerals, montmorillonite sorbed more ibuprofen than kaolinite and goethite, with sorption capacity increasing in the order goethite (2.2 mg/g) \ kaolinite (3

“…Therefore, we proposed that the hydroxyl and carbonyl groups play pivotal roles in the adsorption process. In addition, in view of the higher adsorption capacity of CA fibers compared to activated carbon or other materials with abundant numbers of these groups, 28 the possibility of synergistic effects between the functional groups and the molecular structure of the CA fibers should be studied in depth.…”

“…27−29 Behera et al 28 studied the TCS sorption capacity of activated carbon, kaolinite, and montmorillonite. Cho et al 30 studied the effects of solution chemistry on the adsorption of TCS, and a sorption capacity up to 105.02−558.26 mg g −1 was found for carbon nanotubes.…”

Ionic Liquid Assisted Electrospun Cellulose Acetate Fibers for Aqueous Removal of Triclosan

ABSTRACT:The cellulose acetate (CA) membrane prepared via electrospun was innovatively utilized as fiber-adsorbent for the separation of aqueous triclson (TCS). It was found that the presence of the room temperature ionic liquid (RTIL) in the precursor amplified electric force toward the CA-solution, thereby benefiting the formation of CA fibers. The as-spun CA fibers exhibit excellent adsorptive performance toward TCS, with fast adsorption kinetics, and the maximum adsorption capacity achieved to 797.7 mg g −1 , which established much better performance in contrast to conventional adsorbents. We proposed that the adsorption of TCS onto CA fibers was primarily facilitated by the hydrogen bonding between the abundant carbonyl, hydroxyl groups of CA surface, and the hydrogen atoms of phenol functional groups in TCS molecular.
