“…At equilibrium, the acid red quantity in the aqueous medium was photometrically measured [11]. It was observed when the % E was measured for the acid red adsorption onto the AC-COOH in situ and ex situ, there was a remarkable reduction in % E as the pH values increased as shown in Figure 8a.…”

“…PES-NH2 was prepared with two steps process reactions, a nitration reaction followed by a reduction reaction, following a procedure done by Haider et al [11] as shown in Scheme 1a. First for the nitration reaction, 2 g of PES was added to a mixture of 25 mL (H2SO4) and 10 mL of (HNO3) at 65 °C for 5 h. Then, the reaction mixture solution was ended by pouring the reaction solution into an ice bath filled with cold deionized distilled water (D.D.W).…”

Aminated polyethersulfone (PES-NH 2 ) has been synthesized and used with carboxylated activated carbon (AC-COOH) as an adsorbent using two different methods: in situ and ex situ techniques. The chemical modification of polyethersulfone (PES) to introduce -NH 2 functions was used to overcome the hydrophobicity of PES which maximizes its use in water treatment applications whereas applying AC-COOH to this polymer provides a promising effective method as an adsorbent-separation technique to remove dye pollutants from wastewater. The structure and characterization of aminated polyethersulfone with carboxylated activated carbon (PES-NH 2 -AC-COOH) were identified using proton nuclear magnetic resonance ( 1 H-NMR), Fourier transform infrared (FT-IR spectroscopy), X-ray diffraction (XRD), thermal analysis (TA), and a scanning electron microscopy (SEM). The performance of PES-NH 2 in situ and ex situ with AC-COOH was tested for the adsorption of cationic (methylene blue) and anionic (acid red 1) dyes from an aquatic environment. The results of the study showed a better thermal stability for the PES-NH 2 with 20% AC-COOH with both in situ and ex situ techniques as well as an excellent adsorption performance in comparison with the bare PES-NH 2 . The resultant polymers displayed significantly high adsorption rates for the acid red dye (60% and 68%) and methylene blue dye (61% and 88%) by PES-NH 2 with AC-COOH using in situ and ex situ techniques, respectively, in comparison with the control (PES-NH 2 ) which showed lower adsorption rates for both dyes (21% for acid red and 33% for methylene blue). Lastly, the study experimental measurements found the most suitable model to describe the kinetic behavior of the acid red dye adsorption by our developed polymer (by PES-NH 2 with AC-COOH) to be the pseudo-second-order kinetic model.

“…The gravity force allowed the enzyme to fill the vacancies of membrane pores [27,28]. Chauhan et al, Gupta et al, and Wang et al have done lipase immobilized onto several kinds of membranes, and they found that the membrane surfaces had some beads in clusters [24][25][26]. Regarding the differences of SEM images shown in Figure 4, it can be concluded that lipase was successfully immobilized into the membrane [30].…”

“…The FTIR spectrum of the synthesized PES was presented in Figure 1. The FTIR spectrum of the synthesized PES showed the characteristic peaks of PES at 1234.44 cm -1 and 1103.28 cm -1 corresponded to the C-O-C bonds; while peaks at 1184.29 cm -1 and 1149.57 cm -1 represented the symmetric bond vibration of sulfonate (-SO2-) groups and peaks at 1010.70 cm -1 showed the aromatic vibrations [23][24]. The elucidation structure of the synthesized PES was performed using 1 H-NMR measurement and its spectrum was presented in Figure 2.…”

“…So, the PES has been used as a matrix in many immobilization systems for Candida rugosa, Comamonas testostroni, Bovine Serum Albumin (BSA), heparin, and TiO2 [11][12][13][14][15]. Furthermore, the synthesized PES derivative was used as one of the components in the matrix used for the Cal-B immobilization and showed good results in Cal-B catalysis activity and has better performance compared to previous studies [21][22][23][24][25].…”

Candida antarctica lipase B (Cal-B) has been widely used in the hydrolysis reaction. However, it has some weaknesses, such as: forming of the heavy emulsion during the process, which is difficult to resolve and has no reusability. Therefore, it needs to be immobilized into a suitable matrix. One of the suitable supporting materials is polyethersulfone (PES) and its synthesis becames the objective of this paper. The PES was synthesized via a polycondensation reaction between hydroquinone and 4,4'-dichlorodiphenylsulfonein N-methylpyrrolidone (NMP) as solvent using Microwave Assisted Organic Synthesis (MAOS) method at170 °C for 66 minutes using an irradiation power of 300 watt. The synthesized PES was characterized by FTIR and 1 H-NMR (500 MHz, DMSO-d6). Then the PES membrane was prepared from 20% of the optimized mixtures of PES, PSf (polysulfone), and PEG (polyethylene glycol) dissolved in 80% NMP. The Cal-B was immobilized on the PES membrane by mixing it in a shaker at 30 °C and 100 rpm for 24 h using phosphate buffered saline (PBS). The identification of the immobilized Cal-B was done by using FTIR-ATR spectroscopy and SEM micrographs. The results of Lowry assay showed that the 'Cal-B immobilized' blended-membrane has a loading capacity of 91 mg/cm 2 in a membrane surface area of 17.34 cm 2 . In this work, the activity of immobilized Cal-B was twice higher than the native enzyme in p-NP (p-Nitrophenolpalmitate) hydrolyzing. The results indicated that the synthesized PES showed a good performance when used as a matrix in the immobilization of Cal-B.
