Adsorption Behavior of Arsenic to an Isolated Ferric Ion Combined on Chelate Resin

Abstract

Adsorption behavior of As(V) and As(III) to an isolated ferric ion combined with Chelex 100 suggested that an isolated ferric ion combined with organic substances plays an important role in the uptake of arsenic in the pedosphere in addition to ferric hydrous oxides (Fe2O3·nH2O) which are ubiquitous inorganic polymers.

Novel design of amine and metal hydroxide functional group modified onto sludge biochar for arsenic removal

“…Recent research focused on the use of possible adsorbents, many adsorbents were used for arsenic adsorption based on agriculture and industrial waste, surfactants, carbon-based materials, polymers and metal oxides (Kurniawan et al 2012;Ray & Shipley 2015). Especially, metal oxides such as iron-doped amino-functionalized sawdust (Hao et al 2016), isolated ferric ion combined on chelate resin (Aacharya et al 2017), magnetic gelatin modified biochar (Zhou et al 2017), iron hydroxide/ manganese dioxide (Xiong et al 2017), activated carbon-alumina composites (Karmacharya et al 2016), zeolite synthesized from cenospheres (Markandeya et al 2021), zero-valent iron nanoparticles (Dong et al 2012;Bhowmick et al 2014), silver nanoparticles (Bhardwaj et al 2021), TiO 2 (Xu et al 2010), CeO 2 (Feng et al 2012), CuO (Reddy et al 2013), Fe 2 O 3 (Tang et al 2011a(Tang et al , 2011b, Fe 3 O 4 (Akin et al 2012), CaO (Olyaie et al 2012), ZrO 2 (Cui et al 2013), GNPs/CuFe 2 O 4 (La et al 2017), metal-organic frameworks (Rani et al 2020) and have been extensively studied in aqueous solution for arsenic treatment due to their high affinity with arsenic species, low cost and adsorption capability tunability.…”
