“…Thus, the adsorption behavior of SDBS on Fe 2 O 3 -VR was conrmed for multilayer adsorption. 44 At the same time, 1/n ¼ 0.715 < 1 in the Freundlich model, which revealed that the adsorption process of Fe 2 O 3 -VR for SDBS was spontaneous. 45 In addition, in the Langmuir model, the value of K L was between 0 and 1 indicating that the adsorption is favorable.…”

“…In general, adsorption is the foremost separation method because of its feasibility, low cost, and simplicity of operation. Many adsorbents including activated carbon, 16 zeolites, 17 chitosan, 18 mesoporous silica nanoparticles 19 and fly ash based geopolymer 20 have been used for SDBS removal from wastewater. In recent years, volcanic rocks (VR) have also been widely used in effluent disposal.…”

“…Furthermore, pore diameter intuitively reflected the pore enlarging phenomenon since the pore diameters of CMSN and E-CMSN were 2.2 nm and 4.3 nm. The pore enlargement effect of E-CMSN was obvious since most common pore diameter of mesoporous silica nanoparticles was in the range of 2 to 3.5 nm [28,29].…”

Large mesopores of chiral silica nanoparticles applied as drug carrier are worth studying. In this study, chiral mesoporous silica nanoparticles (CMSN) and enlarged chiral mesoporous silica nanoparticles (E-CMSN) with a particle size from 200 to 300 nm were synthesized. Fourier transform infrared spectrometer (FTIR), circular dichroism spectrum, scanning electron microscopy (SEM), transmission electron microscope (TEM), and nitrogen adsorption/desorption measurement were adopted to explore their characteristics. The results showed that the surface area, pore volume, and pore diameter of E-CMSN were higher than those of CMSN due to enlarged mesopores. Poorly water-soluble drug nimesulide (NMS) was taken as the model drug and loaded into carriers using adsorption method. After NMS was loaded into CMSN and E-CMSN, most crystalline NMS converted to amorphous phase and E-CMSN was superior. The anti-inflammatory pharmacodynamics and in vivo pharmacokinetics results were consistent with the wetting property and in vitro drug dissolution results, verifying that NMS/E-CMSN exhibited superior NMS delivery system based on its higher oral relative bioavailability and anti-inflammatory effect because its enlarge mesopores contributed to load and release more amorphous NMS. The minor variations in the synthesis process contributed to optimize the chiral nano-silica drug delivery system.

“…Adsorption is a convenient, efficient, environmentally friendly, easy of operation and cost-effective process. [15][16][17][18] Different adsorbents such as chitosan, [19] fly ash-based geopolymer, [6] silica, [20] zero-valent iron nanoparticles, [21] bentonite, [22] cellulosic surface, [23] alumina, [24] zeolites [25] and chromium leather waste [26] were utilized for the adsorption of surfactants from aqueous solutions. Carbon-based adsorbents such as activated carbon, [8,27,28] carbon black, [29,30] multi-wall carbon nanotubes (MWCNTs) [31][32][33] and graphene oxide [34,35] have been suggested for pollutants removal.…”

The objective of the study is to investigate the potential of carbide-derived carbon (CDC) for the adsorptive removal of nonionic t-octylphenoxy poly ethoxy ethanol (TX-100), anionic sodium dodecylbenzene sulfonate (SDBS) and cationic 1-hexadecylpyridinium bromide (HDPB) surfactants from water. The CDC was characterized using TEM, SEM, FTIR, BET, EDS, XPS methods and zeta potential measurements. The effects of adsorption parameters included initial surfactant concentration, contact time, temperature, and pH of the feed solution were evaluated. The adsorption capacity and mechanism were determined by modeling the isotherm, kinetic and thermodynamic data. The kinetics results demonstrated that the adsorption of the surfactant by CDC obeys the pseudo 2 nd order model. The thermodynamic results have shown that surfactants adsorption by CDC is an endothermic and spontaneous process. The Sips model agreed with the adsorption isotherm data of SDBS with R 2 of 0.987, while both Freundlich and Redlich-Peterson models comply well with adsorption data for TX-100 and HDPB. The hydrophobic and electrostatic interactions were found the dominant mechanisms of the adsorption of the surfactant by CDC. The adsorption capacities of CDC were found to be 442.4, 462.0 and 578.4 mg/g for SDBS, HDPB and TX-100, respectively.
