Calcined sandstone and calcined laterite were tested as adsorbent at a low cost for the removal of arsenic (As) from the drinking water. The natural materials were collected in Cote d'Ivoire, washed and then dried at a temperature of 60 ° C and finally calcined in an oven at the atmospheric air in several temperatures 300 ° C, 400 ° C, 500 ° C, 600 ° C and 700 ° C. The study of adsorption of the arsenic was realized for the various adsorbates. It showed that the biggest efficiency of the…

Removal of Arsenic from Simulated Groundwater Using Calcined Laterite as the Adsorbent
Arsenic in groundwater poses a health hazard for rural areas all over the world, especially in developing countries. This paper reports the findings of a batch study performed to identify the best
Laterite, Sandstone and Shale as Adsorbents for the Removal of Arsenic from Water
This study aims at exploring arsenite (As (III)) removal from water using naturally available rocks (laterite, sandstone and shale) in Cote d’Ivoire. The study focused on the adsorbent dose,
Adsorption of As(III) from aqueous solutions by iron oxide-coated sand.
Arsenic removal using mesoporous alumina prepared via a templating method.
TLDR
MA with a wide surface area, uniform pore size, and interlinked pore system can be used as an efficient adsorbent for the removal of arsenic.
Algerian natural montmorillonites for arsenic(III) removal in aqueous solution
The adsorption of As(III) from aqueous solutions using naturally occurring and modified Algerian montmorillonites has been investigated as a function of contact time, pH, and temperature. Kinetic
Adsorption of arsenic from aqueous solution on naturally available red soil.
TLDR
Red soil could be used as effective filter medium for removal of arsenic from water and Equilibrium studies show that As (III) ions have high affinity towards red soil even at very low concentration of arsenite.
Kinetics of Phosphate Sorption and Desorption by Synthetic Aluminous Goethite Before and after Thermal Transformation to Hematite
Abstract Goethite is an important component of many soils and its transformation to hematite by fire may affect phosphate retention. This study deals with the kinetics of phosphate sorption and
