Enhanced adsorption of arsenic using calcined alginate

The calcination process create An adsorbent of bead type to remove arsenic (As) was developed by calcination of sodium alginate and polyvinyl alcohol containing a powder form of alum sludge. The adsorbent was evaluated in terms of adsorption kinetics, capacities in batch tests and by a column study.

Arsenic Removal from Aqueous Solutions Using Fe3O4-HBC

Jun 26, 2014 This study suggests that the selective calcination process could be useful to improve the adsorbent efficiency for enhanced arsenic removal from contaminated water. Introduction Arsenic is an ubiquitous element that has been recognized to exist in four oxidation states (−3, 0, +3 and +5).

Enhanced adsorption of arsenic onto alum sludge modified

Mar 01, 2018 In comparison, calcination at 300 °C removed organic matter efficiently without changing the structure of the adsorbent, and showed greater adsorption capacity for As(V). The results suggested that calcination is a suitable process for producing alum sludge-based adsorbent for As(V) removal.

Adsorption of arsenic on the reused sanding wastes

Aug 05, 2009 The removal capacity of arsenic(III), As(III), by the reused sanding wastes prepared at different calcination temperatures was investigated in this study. As a pretreatment process for the preparation of the reused material from raw sanding wastes (RSW), calcination was performed in a furnace at 550, 750, 900, 1100, and 1300 °C.

Arsenic removal from water using calcined Mg–Al layered

Arsenic (As) in drinking water and its related toxicology are serious concerns nowadays. Development of better techniques related to removal of As from drinking water is an urgent need. Layered double hydroxide (LDH) or hydrotalcite-like compound with the general formula [M 1− 2+ M 3+ (OH)2] x+ A x−·nH2O can be considered as a good adsorbent for the removal of toxic As from water.
