Removal of chromium from aqueous solutions using a palm kernel shell adsorbent
Open accessAbstract
ABSTRACT The presence of chromium (VI) or its compounds in water is a result of its uses in modern society. The presence of toxic chromium (VI) in large quantities will adversely affect and interfere with many beneficial uses of water. Adsorption is an effective approach used to remove chromium (VI). Chemical characteristics of the palm kernel shell (PKS) were optimized by hydroxyl pretreatment followed by quaternization for the adsorption of chromium (VI). It was observed that the chemically modified palm kernel shell (CMPKS) showed an effective adsorption property, with a maximum capacity of 19 mg/g at pH 2 and 17 mg/g at pH 6 and 4. The kinetics model with pseudo-first and pseudo-second orders were studied, along with Langmuir and Freundlich isotherms. The Langmuir model and the pseudo-second-order model were observed to be a better fit for this process. Scanning electron microscopy analysis showed significant changes in the surface morphology of CMPKS, with changes in the projection and porous surfaces.

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.
