Abstract

Oil seed, which is a secondary product in phytoremediation, contaminated with heavy metals should be disposed of in an appropriate fashion. In this study, heavy metal concentrations found in oilseed rape and peanut oils were below 0.1 mg kg(-1) after extractions, being found most of the heavy metals in meals rather in oils. Extraction experiments were carried out to determine the optimum methodology for the removal of Pb and Cd from seed meals using K3C6H5O7, K2C4H4O6 and (NH4)2EDTA. The highest extraction of the Pb and Cd in the seed meals was achieved using 30 mM extractant solutions at 30°C for 24 h and a three-step extraction procedure. K3C6H5O7 and K2C4H4O6 had less impact on the removal of nutrients than (NH4)2EDTA.

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.
