Compared arsenic removal from aqueous solutions by synthetic mixed oxides and modified natural zeolites

Adsorption of heavy metals on natural zeolites: A review

“…The characterization of the magnetically modified zeolites shows that the presence of magnetic compound does not inhibit the natural zeolites frameworks and channels (Kragović et al, 2013b;Liang et al, 2011;Yuan et al, 2018b). Iron, and copper are the metallic compounds used in magnetically modified natural zeolites (Ates et al, 2011;Guaya et al, 2015;Heredia et al, 2019;Li et al, 2011;Neolaka et al, 2022;Vakili et al, 2019). Several authors reported higher pollutant adsorption capacity by magnetically modified natural zeolites because more adsorption sites are present (Liang et al, 2011;Lv et al, 2014;Simsek et al, 2013;Yuan et al, 2018), They reported Pb adsorption capacity of 84.00 mg/g and 66.96 mg/g for MMZ and Na-zeolite, respectively.…”

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…However, the procedures for their characterisation have quickly matured, leading to token details being mentioned in manuscripts. A number interesting papers utilising the absorptive power of zeolites to remove arsenic from natural 105 and deep well waters, 106 hexavalent chromium in wastewater 107 and mercury from flue gas 108 were reported. In each study, XRF was the preferred technique for characterising the elemental composition.…”

Eliminación de Contaminantes Orgánicos en Agua Empleando Nanomateriales Catalíticos Fotoactivos

“…Los catalizadores obtenidos a partir de estos materiales están siendo evaluados no sólo en la fotodegradación de contaminantes, sino también en otras aplicaciones. Junto a Heredia et al [13] se evaluó la capacidad de remoción de As(III) de una serie de catalizadores obtenidos de la modificación de clinoptilolita con Fe (III), figura 6, C.…”
