Abstract

In this study, a synthesized cation exchange resin supported nano zero-valent iron (NZVI) complex forming NZVI-resin was proposed for the decoloration of an azo dye Acid Blue 113 (AB 113), taking into account reaction time, initial dye concentration, NZVI dose and pH. From results, the successful decoloration of the AB 113 solution was observed using a NZVI-resin. Increasing the iron load to 50.8 mg g(-1), the removal efficiencies of the AB 113 concentration increased exponentially. With an initial dye concentration of 100 mg l(-1) and nano iron load of 50.8 mg g(-1), the best removal efficiencies were obtained at 100 and 12.6% for dye concentration and total organic carbon, respectively. Color removal efficiency was dependent on initial dye concentration and iron load. Moreover, the removal rates followed modified pseudo-first order kinetic equations with respect to dye concentration. Thus, the observed removal rate constants (k) were 0.137-0.756 min(-1) by NZVI loads of 4.9-50.8 mg g(-1). Consequently, the NZVI-resin performed effectively for the decoloration of AB 113 azo dye, offering great potential in the application of NZVI-resins in larger scale column tests and further field processes.

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.
