Carboxymethyl cellulose/carboxylated graphene oxide composite microbeads for efficient adsorption of cationic methylene blue dye
Abstract
An efficient composite adsorbent was fabricated based on carboxymethyl cellulose (CMC) microbeads incorporated carboxylated graphene oxide (GOCOOH) for the adsorptive removal of cationic methylene blue dye (MB). The developed CMC/GOCOOH composite microbeads were characterized by means of FTIR, TGA, SEM, XPS, BET and zeta potential analysis tools. Various parameters affecting the removal of MB dye such as the amount of GOCOOH, initial MB concentration, adsorbent dosage, pH and medium temperature were optimized using a series of batch adsorption experiments. The experimental data of the adsorption process were more fitted to Langmuir isotherm (R2 = 0.998) with a maximum adsorption capacity of 180.32 mg/g and followed the pseudo-second order kinetic model. Moreover, the adsorption of MB dye onto CMC/GOCOOH composite microbeads was an exothermic process with a maximum capacity at pH 10. Besides, the fabricated adsorbent exposed also better reusability for nine repetitive cycles with highly adsorption properties. The gained results imply that the CMC/GOCOOH microbeads could be potentially applied as an effective and reusable adsorbent for MB dye removal from aqueous 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.
