Simultaneous reduction and adsorption of arsenite anions by green synthesis of iron nanoparticles using pomegranate peel extract

Purification of As(iii) through oxidation of siderite and As(iii) by dissolved oxygen: behavior and mechanism

“…81,82 Reduction of Fe(III) oxides mainly took place under reducing conditions during the discharge of groundwater into surface water, but oxidation of both As(III) and Fe(II) occurred during the recharge of surface water to groundwater. Oxidation not only resulted in the formation of Fe(III) oxides, 83 but also promoted As(III) removal via adsorption, oxidation, and coprecipitation. Nevertheless, further studies, with the aid of in situ characterization techniques and theoretical calculation models, are still needed to elucidate the binding sites and energy between Fe(III) oxides from siderite transformation and As to develop a theoretical model of As(III) adsorption, oxidation, and co-precipitation.…”

Sonochemical-Assisted Biogenic Synthesis of Theophrasite β-Ni(OH)2 Nanocluster Using Chia Seeds Extract: Characterization and Anticancer Activity

“…Various techniques have been developed for the production of metal nanoparticles with high energy consumption and longer reaction time strategies such as chemical deposition [ 17 ], sol-gel technique [ 18 ], co-precipitation [ 19 ], green methods [ 20 , 21 ], hydrothermal [ 22 ], solvothermal and sonochemical synthesis [ 23 ]. The sonochemical-assisted synthesis method has several advantages, such as morphology control, homogeneity of mixing, and decreased product agglomeration [ 24 ].…”
