Adsorption characteristics of As(V) on iron-coated zeolite
Abstract
The sorption characteristics of arsenic(As(V)) on iron-coated zeolite (ICZ) were investigated through batch and column studies. As(V) was completely removed within 30 min in a concentration of 2mg/l, with a 100g/l dose of ICZ. Optimum dose of ICZ was 33.3g/l at a concentration of 20.12 mg/l and the effect of solution pH was negligible at a pH range of 3.0<pH<10.0. Langmuir Isotherm Model was suitable to explain the sorption characteristics of As(V) onto ICZ. The co-presence of sulfate ions inhibited sorption of As(V) because of competitive adsorption. The adsorption capacity of ICZ for As(V) was 0.68 mg/g. Based on the result, ICZ is a suitable material to treat the mine drainage or wastewater bearing As(V).

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.
