“…The correlation coefficients of Langmuir model are shown in Table 2, and these suggest a positive evidence which can confirm the sorption of TCS on CMFC. Besides, the maximum monolayer (Behera, Oh, & Park, 2010;Cho, Huang, & Schwab, 2011;Hu et al, 2009;Lei, Hu, & He, 2013). capacity Q m (120.48 mg/g) is calculated by Langmuir model in Table 2.…”

Studying the removal of rhodamine B (RB) dye by using zeolite 13X molecular sieves supported by Fe 2 O 3 nanoparticles (denoted as Fe 2 O 3 -13X) is the main objective of this study. Fe 2 O 3 -13X was synthesized and modified by the addition of sodium dodecyl sulfate (SDS). e prepared Fe 2 O 3 -13X was characterized by XRD, TEM, SEM, and zeta potential. e effects of the solution pH, SDS amount, contact time, initial dye concentration, and adsorbent dosage on the removal efficiency of RB were studied. A maximum removal efficiency of 99.3% was achieved. e adsorption equilibrium data of RB were fitted using the Freundlich model, yielding the maximum adsorption capacity of 89.3 mg/g. e findings revealed that the RB adsorption onto Fe 2 O 3 -13X modified with SDS (Fe2O3-13X-Ms) was described by a pseudo-second-order kinetic equation. e results reported in this paper indicate that a high RB removal percentage was attained by adding SDS to Fe 2 O 3 -13X.

“…Previous research has suggested that BS-biochar (similar to the BS-biochar produced in this study) contains C-O bonds on the surface, such as those found in phenols, esters, and carboxylic functional groups (Gasco et al, 2005;Tong et al, 2016). Polar oxygen-containing functional groups such as carboxyl and phenol groups likely interacted with phenyl groups on TCS molecules via hydrogen bonding, and aromatic groups present on both the adsorbent and adsorbate surface may have also contributed to p-p stacking (Lei et al, 2013;Tong et al, 2016).…”

“…2 suggest that TCS removal was decreased likely due to direct competition for adsorption sites on the BS-biochar surface by E2 and SMX molecules. Adsorption mechanisms such as hydrogen bonding and p-p interactions between aromatic rings on the adsorbent surface and adsorbate p-electrons likely contributed to adsorption of all organic micropollutants in solution (Monsalvo et al, 2011;Lei et al, 2013;Tong et al, 2016), thereby decreasing the fraction of TCS removed by BS-biochar. Similarly, Jung et al (2013) reported competitive adsorption effects between endocrine disrupting compounds (including SMX and BPA) for adsorption sites on PAC and biochar derived from loblolly pine chips ( Jung et al, 2013).…”

Micropollutants, including antibiotics, hormones, pharmaceuticals, and personal care products, are discharged into the environment with liquid and solid effluent streams from water resource recovery facilities (WRRFs). The objective of this research was to determine whether biosolids-derived biochar (BS-biochar) could be used as a sorbent in continuous flow-through columns to remove micropollutants as a polishing step for wastewater treatment. Triclosan (TCS) was selected as a representative micropollutant due to frequent detection in liquid effluents, residual biosolids, and surface waters. Bench-scale column experiments were conducted to determine the effect of flow rate and competition due to the presence of other organic micropollutants and inorganic nutrients on TCS adsorption to BS-biochar. TCS removal efficiency was compared in Milli-Q water and secondary wastewater effluent by using two commercial adsorbents: a granular activated carbon and a wood-based biochar. Increased removal of TCS was observed at lower flow rates (2.6 gpm/ft 2) compared with higher flow rates (10.3 gpm/ft 2). Presence of inorganic nutrients (NH 4 + and PO 4 3-) and organic micropollutants 17b-estradiol and sulfamethoxazole decreased adsorption of TCS to BS-biochar. TCS was sorbed to BS-biochar in wastewater, but percent removal decreased in wastewater relative to Milli-Q water. This study demonstrated that BS-biochar can remove TCS from wastewater in continuous flow-through columns, although to a lesser extent than activated carbon. An additional benefit of using BS-biochar is that WRRFs could reactivate biochar on-site by using a pyrolysis reactor.
