“…Furthermore, the maximal adsorption capacity (53.476 mg/g) of BKBP was successfully predicted by Langmuir adsorption isotherms analysis (Table 3), which was higher than the ability of okra superfine powder around 18.75 mg/g (Chen et al, 2015b), and carrot pomace insoluble dietary fiber around 30 mg/g (Yu et al, 2018), but lower than thyme ( Thymus vulgaris L.) powder of 84.74 mg/g (Salehi et al, 2018). Besides, the value of 1/ n (0.697) obtained from the Freundlich model was less than unity, indicating the favorability of the adsorption.…”

“…Thus, superfine BKBP might act as a novel nutraceutical additive/excipient in tablets, such as simvastatin, to provide synergistic effects for lowering serum cholesterol level (Swami et al, 2010). Besides, it would be also interesting to employ the BKBP as the potential biosorption materials in the developments of low cholesterol milk or milk beverages (Oliveira et al, 2015), and even in the extracorporeal perfusion to immediately reduce the content of the lipids in the blood (Salehi et al, 2018).…”

Black kidney bean (Phaseolus vulgaris L.) powder (BKBP) with particle sizes of 250–180, 180–125, 125–75, 75–38, and <38 μm was prepared by using coarse and eccentric vibratory milling, respectively. Physicochemical properties, cholesterol adsorption, and antioxidant activities of powders were investigated. Size and scanning electron microscopy analyses showed that particle size of BKBP could be effectively decreased after the superfine grinding treatment, and the specific surface area was increased. Flow properties, hydration properties, thermal stability, and cholesterol adsorption efficiency significantly improved with the reducing of particle size. The superfine powder with sizes of 75–38 or <38 μm exhibited higher antioxidant activity via 2,2-diphenyl-1-picryhydrazyl, hydroxyl radical-scavenging, and ferrous ion-chelating assays. The results indicated that the BKBP with a size of <38 μm could serve as a better potential biological resource for food additives, and could be applied for the development of low-cholesterol products.

Flow properties, hydration properties, thermal stability and cholesterol adsorption efficiency significantly improved with the reducing of particle size. The superfine powder with sizes of 75-38 or < 38 μm exhibited higher antioxidant activity via DPPH, hydroxyl radical-scavenging, and ferrous ion-chelating assays. The results indicated that the BKBP with a size of < 38 μm could serve as a better potential biological resource for food additives, and could be applied for the development of low-cholesterol products.

“…The linear form of the Dubinin–Radushkevitch ( D – R ) isotherm is as follows 43 where q m (mg g –1 ) is the theoretical saturation capacity, β (mol 2 J –2 ) is the constant related to the mean free energy of adsorption, and ε is the Polany potential that is equal to 44 In this equation, R (J mol –1 K –1 ) and T (K) are the ideal gas constant and the absolute temperature, respectively. The adsorption average free energy ( E , J mol –1 ) is related to the change of free energy when 1 mole of the adsorbate transfers from infinity to the surface of the adsorbent in the solution.…”

The graphitic carbon nitride/tin oxide (g-C 3 N 4 /SnO 2 ) nanocomposite synthesized under microwave irradiation was used for adsorptive removal of sulfur-containing dibenzothiophene (DBT) from Tehran vehicular gasoline. High-resolution transmission electron microscopy, X-ray powder diffraction, energy dispersive X-ray spectroscopy, Brunauer–Emmett–Teller, Fourier-transform infrared spectroscopy, and field emission scanning electron microscopy techniques determined the adsorbent characteristics, and gas chromatography with a flame ionization detector determined the DBT concentration of the samples. Application of the experimental data into the solid/fluid kinetic models indicated a chemisorption control regime that increased the removal of sulfur from the commercial samples used. A pseudo-second-order reaction with the rate constant of 0.015 (g mg –1 min –1 ) and total conversion time of 316 min described the adsorption process. Based on the real fuel results, the adsorption capacity of the g-C 3 N 4 /SnO 2 adsorbent reached 10.64 mg S g –1 adsorbent at equilibrium conditions. This value was the highest adsorption capacity obtained so far for a commercial gasoline sample. The g-C 3 N 4 /SnO 2 nanocomposite could, therefore, be introduced as an inexpensive, easily obtainable adsorbent that can significantly remove the sulfur from the vehicular gasoline fuels.
