“…The non-linear form of Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, and Sips models [52] was adopted to analyze the adsorption equilibrium data of CUR onto the CoFe2O4/GO-ADH-CMC (at three temperatures of 298, 308, and 323 K) and CoFe2O4/GO (at the temperature of 323 K).…”

In this study, a pH-responsive magnetic drug delivery system was prepared by cross-linking of Cofe2O4/graphene oxide to carboxymethyl cellulose (CMC) biopolymer with adipic acid dihydrazide (ADH) and then investigated for loading and release of a poorly water-soluble anti-cancer drug, curcumin (CUR). The CoFe2O4/GO-ADH-CMC bio-nanocomposite was characterized by FE–SEM/EDX, TEM, FT–IR, XRD, TGA, VSM, and zeta-potential techniques. The highest amount of drug loading was achieved as 23.7 mg g–1 at 323 K, pH 6.0, and 120 mg L–1 CUR concentration. The study of adsorption isotherms revealed that the Sips model was best fitted to the equilibrium data (R2 > 0.997), which indicated the contribution of both chemisorption and physisorption in drug loading. Furthermore, the release profile of CUR from drug-loaded CoFe2O4/GO-ADH-CMC was studied in mimicking the endosomal (pH = 5.6) and physiological (pH = 7.4) conditions. After 24 h, the maximum cumulative releases were found to be 86 and 38% at pH = 5.6 and 7.4, respectively. Also, the Peppas-Sahlin kinetic model was followed for the release data. The MTT assay exhibited good biocompatibility of the CoFe2O4/GO-ADH-CMC. The results implied that CoFe2O4/GO-ADH-CMC magnetic bio-nanocomposite might be utilized as a potentially safe carrier with the continuous and slow release of CUR.

“…In the future, coal will still play a major energy role in China. North China is China's main coal mining area, and the coal produced is stacked in open-air coal storage yards [1][2][3][4]. Due to the cold and dry climate and strong wind in northern China, it is easy for coal dust piled in the open air to be blown by the wind, forming a source of air pollution [5][6][7].…”

In an effort to control dust pollution in open-air environments such as pit coal mines and coal transportation systems, a new dust suppressant with a cross-linked network structure was prepared. Graft copolymerization of soy protein isolate (SPI) and methacrylic acid (MAA), using potassium persulfate (KPS) as the initiator and hexametaphosphoric acid (SHMP) as the cross-linking agent, formed the network structure. The optimal MAA/SPI mass ratio for the dust suppressant was determined through a single factor experiment to be 3:4, with 0.8 and 0.2 g of SHMP and KPS, respectively. The grafting reaction required 30 min at 60 ℃. Scanning electron microscopy, energy-dispersive x-ray spectroscopy, Fourier-transform infrared spectroscopy, and differential scanning calorimetry were used to characterize the structure and application performance of the dust suppressant. The experimental results showed that the graft copolymerization reaction successfully formed the desired cross-linked network, and that when the cross-linked network material was sprayed on coal dust it formed a dense, solidi ed shell, which effectively resisted wind erosion and served as a dust suppressant. The average reduction of the total suspended particulate matter of an open-air coal pile reached 79.95%, demonstrating effective dust suppression.
