Removal of Arsenic(V) from Aqueous Solution Using Industrial Solid Waste: Adsorption Rates and Equilibrium Studies
Abstract
Industrial solid wastes can be recycled as nonconventional adsorbents, if they are nontoxic, to reduce the cost of wastewater treatments. “Waste” Fe(III)/Cr(III) hydroxide, generated electrolytically in the treatment of Cr(VI) containing wastewaters in a fertilizer industry was used for the adsorption of arsenic(V) from aqueous solution. Parameters studied include arsenic(V) concentration, agitation time, adsorbent dosage, adsorbent particle size, temperature, and pH. The adsorption capacity was evaluated by using both Langmuir and Freundlich isotherm models. The adsorption followed a first-order rate expression. Adsorption of As(V) was independent of the initial pH (3−10) of the aqueous solution. Temperature studies showed that the adsorption process was endothermic in nature. Desorption of As(V) from spent adsorbent was also investigated using NaOH solutions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
