Characterization of arsenite (As(III)) and arsenate (As(V)) sorption on synthetic siderite spherules under anoxic conditions: Different sorption behaviors with crystal size and arsenic species

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

“…S10a and b †), which is the typical micro-morphological characteristic of siderite. 70 At an initial As(III) concentration of 20 mg L −1 , the surface of reacted siderite became rough in the absence of Environmental Science: Nano Paper DO. However, some needle-like or rod-shaped materials appeared on reacted siderite in the presence of DO.…”

High-efficiency removal of As(iii) from groundwater using siderite as the iron source in the electrocoagulation process

“…27,28 Moreover, it forms complexes with water contaminants for purication purposes and facilitates REDOX reactions. Despite previous investigations on siderite's efficacy in removing water arsenate and arsenate through adsorption processes, 29,30 limited studies have explored its potential as an iron source for electrocoagulation reactions.…”
