“…4A). This observation is confirmed by several adsorbents in the previous literature [8][9][10][11][12][13]. As the initial pH increased to 3.5 sorption capacity increased to more than 74 % and decreased in the initial pH range above 3.5 and 12 (>74 and 11.5 %).…”

“…Although the last influence of these type of contaminants on population health remains up to this time a field of intense study, their uptake from wastewater and aquatic media is definitely an important challenge for world-wide government agencies and scientists. Indeed, numerous attempts including physical and chemical technologies comprising advanced oxidation processes (AOPs) such as oxidation, TiO 2 photocatalysis, perozonation, ozonation, direct photolysis, solar photocatalysis, Fenton reactions and ultrasonic irradiation, electrochemical oxidation, electrocoagulation, membrane separation, and adsorption have been made to improve adsorbents in order to uptake emerging contaminants from drinking water [8][9][10][11][12][13][14]. However, the high-cost of the systems, the uncontrolled reaction conditions, limitation on being used in large scale and the production of secondary contaminants are the main drawbacks of the considered techniques.…”

A polar nano-dendritic adsorbent containing amine groups (SAPAMAA) was synthesized onto the nanoparticles of SiOAlO and its uptake of salicylic acid (SA) from the synthetic and real water was investigated. The synthesized nanomaterials were fully studied by nuclear magnetic resonance spectrum (H NMR and C NMR), Fourier transform infrared spectroscopy (FT-IR), zeta potential (ζ), inductively coupled plasma atomic emission spectroscopy (ICP-AES), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) and elemental analysis. Various parameters such as the effect of the contact time, adsorbent dosage, initial SA concentrations, effect of solution's temperature, interfering ions, the hydrophobicity of the nanoadsorbent and initial pH were assessed. The contact time to approach equilibrium for higher adsorption was 15min (252.8mgg). The isotherms could be fitted by Sips model (with the average relative error of 6.6) and the kinetic data could be characterized by pseudo-second-order rate equation (with the average relative error of 13.0), implying chemical adsorption as the ratelimiting step of uptake process which was supported by the experimental data from the effect of interfering ions, zeta potential, and altering of the adsorbent's hydrophobicity. The uptake capacities decreased with temperature increasing, and showed that the uptake of SA was chemically exothermic in nature between 15 and 80°C. In addition, the spent SAPAMAA could be regenerated by the removal of adsorbed SA with NaOH and ethanol to regain the original SAPAMAA, the regenerated SAPAMAA also exhibited the high adsorption capacity after 10 runs. Moreover, SAPAMAA could also be applied to uptake SA from a real water (Anzali lagoon water). We envisage that the prepared nano-dendritic with remarkable characteristics such as environmentally friendly, low-cost, easy preparation in large quantity, high mechanical and chemical stability will play a significant role in developing a new generation of emerging contaminants adsorbent.

“…Cellulose triacetate (CTA), that has an average DS above 2.8 (Heinze & Liebert, 2001), is one of the most important cellulose esters due to its low toxicity and low flammability. It, therefore, has an important role in industrial applications (Goda, Sreekala, Gomes, Kaji, & Ohgi, 2006;He et al, 2015;Jandura, Riedl, & Kokta, 2000;Kiso, Kitao, & Nishimura, 1999;. CTA could be used in the removal of organic pollutants from water (Dai et al, 2005;Vinturella, Burgess, Coull, Thompson, & Shine, 2004).…”

“…The results obviously revealed that the imprinted membranes (MICM) showed the higher imprinting effect for BSA than that of the non‐imprinted membranes (NMICM), and had higher permselectivity. Based on the results, it can be assumed that the permeation transport mechanism of the imprinted membranes (MICMs) was in accordance with the selective permeation mechanism, that is, “facilitated permeation driven by preferential sorption of the template due to affinity binding—slower transport of other solutes.” In such a way, BSA could transport through MICM from one imprinted site to another until they entered into the receptor chamber, while the interaction between the non‐imprinted membranes (NMICMs) and BSA was nonspecific binding, and the competitive molecular also nonspecific interacted with MICM. Moreover, MICM had more and larger continue pores and surface areas which maybe were also beneficial for BSA to cross the MICM.…”

A novel supermacroporous molecularly imprinted cryogel membrane (MICM) was prepared via cryopolymerization using a functionalized ionic liquid {(1‐vinyl‐3–(2‐amino‐2‐oxoethyl) imidazolium chloride, [VAMIM]Cl]} as functional monomer. Bovine serum albumin (BSA) was selected as the model protein. The novel membrane has the advantages of several concepts, such as, the easy mass transport of cryogel, the multiple weak interactions of ionic liquid with protein, high selectivity of molecularly imprinted polymer, and continuous separation of membrane separation. The membrane was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrum (FT‐IR), thermal gravimetric analysis (TGA), and X‐ray photoelectron spectroscopy (XPS). Ovalbumin (Ova), lysozyme (Lys), and bovine hemoglobin (BHb) were selected as reference proteins to examine the selective recognition of BSA on MICM. The results of SEM images and the swelling ratios showed that MICM had a larger amount of interconnected supermacropores compared with NMICM, which was beneficial for BSA to be adsorbed onto and pass through MICM. The adsorption and permeation results indicated that MICM had better recognition selectivity and permselectivity to the objective protein BSA than NMICM. Overall, the results showed that the functionalized ionic liquid was a good choice to prepare supermacroporous MICM via cryopolymerization for selective recognition of BSA. © 2018 Wiley Periodicals, Inc.
