“…Shells can be made of inorganic components (e.g., silica [56][57][58][59][60] or alumina [61]) or organic molecules such as polymers [62,63] or surfactants [64,65]. These coating can improve particle chemical stability, prevent oxidation, and also provide specific functionalities like selectivity for ion uptake [62][63][64][65] or enhancing the water solubility of hydrophobic contaminants [54,[58][59][60]66].…”

“…A research work carried out by Bagheri et al (2012b) [91] evaluated the thermal stability of the magnetic metal-organic framework ((MOF) = Cu 3 (BTC) 2 (BTC = benzene-1,3,5-tricarboxylate)) and MOF using TGA. According to the TG analysis results, weight loss for MOF was about 72%, and the remaining 28% was related to the presence of Cu 2+ in the MOF structure.…”

Precious metals which include the platinum group, gold, and silver, play indispensable roles in high technology industries of the modern world due to their outstanding physical and chemical properties. As a result of diminishing availability of mineral sources, increasing demand, and environmental concerns, the recovery of precious metals from both leaching and industrial waste solutions is becoming a very important technology. Magnetic solid phase extraction (MSPE) is a technique that has received substantial consideration in the separation and recovery of precious metals because of the many advantages it offers compared to conventional methods. This technique is based on the extraction of different analytes from solutions using solid adsorbents with magnetic properties. This review focuses on different types of magnetic adsorbents, the main procedures used for synthesis, characterization and their application in precious metals recovery based on recently published literatures.

“…Compared to CCD, another RMS-based method, Box-Behnken design, has the advantages of a reduction in the number of experiments and no experiments are performed under extreme conditions [15]. It has been successfully applied for the optimization of various processes, such as solvent extraction [16,17], adsorption [18,19], and material synthesis [20,21].…”

Solid acid catalysts were synthesized from macroalgae Sargassum horneri via hydrothermal carbonization followed by sulfuric acid sulfonation. A three-variable Box-Behnken design and optimization was used to maximize surface acidity. The optimal preparation conditions were found to be at the carbonization temperature of 217 °C, the carbonization time of 4.6 h and the sulfonation temperature of 108.5 °C. Under these conditions, the highest surface acidity achieved was 1.62 mmol g −1 .Physical and chemical properties of prepared solid acid catalyst were characterized by powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, and elemental analysis. The results proved the grafting of -SO 3 H groups on an amorphous carbon structure. The catalyst activity was evaluated by the esterification of oleic acid with methanol. The sample prepared achieved 96.6% esterification yield, which was higher than the 86.7% yield achieved by commercial Ambersyst-15 under the same reaction conditions. Graphical Abstract
