Abstract

The current study portrays a dispersive solid-phase extraction as a silica nanoparticle-covered Graphene Oxide(GO-SiO2) synthesised with some modification as in the literature and developed removal/preconcentration method for selective extraction of some heavy metal in water samples. Flame atomic absorption spectrophotometry (FAAS) was used to measure in optimum conditions for the proposed method. Field emission scanning electron microscope (FESEM) and X-beam diffraction (XRD) were utilised for the characterisation of solid phase. The developed method presents high surface areas for sorption capacity and a low amount of solid phase. The removal percentage was performed at approximately 100% with pH 4 to 10 for all metal ions. According to validation results under the optimised method, the limits of detection (LODs) and quantification (LOQs) were found in the range of 5.8–23.0 µg L−1 and 16.0 − 38.1 µg L−1, respectively. The developed method was applied by using certified reference material (BCR 715) for trueness, which observed high relative recovery with lower than 11.8% relative error except for Pb and Cd. The comparison between the experimental results and the certified reference material indicated that the accuracy of the method is higher than 90%. The proposed method was effectively practised for five water samples with standard addition.

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.
