Removal of chromium(VI) from solution by coconut husk and palm pressed fibres
Open accessAbstract
Removal of chromium(VI) from aqueous solutions by coconut husk fibres (CHF) and palm pressed fibres (PPF) was investigated using batch and column techniques. Batch tests showed that pH range for effective Cr(VI) removal was between 1.5 and 5 for CHF and between 1.5 and 3 for PPF. The adsorption capacities of CHF and PPF were estimated to be 29 and 14 mg Cr g‐1 substrate at pH 2.0. In column studies, breakthrough curves of various columns containing PPF were obtained for various flow rates and bed‐depths and the results were compared with Hutchin's model for adsorption column (1). The results of breakthrough curves of various columns containing mixed media of CHF or PPF in soil system demonstrated that both substrate could also be used as barriers in the landfill to maximize immobilization of toxic metal such as Cr(VI) in leachates.

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.
