Abstract

A dispersive liquid-liquid microextraction ( DLLME ) procedure for determination of Pb(II) in water and tobacco samples has been developed using rac-(E,E)-N,N′-bis(2-chlorobenzylidene)cyclohexane-1,2-diamine as a chelating agent. Factors influencing the efficiency of DLLME have been optimised, including metal solution pH, type and amount of dispersing solvent, type and amount of extraction solvent, amount of chelating agent and sample volume. The optimized conditions for maximum recovery were as follows: sample pH 6; dispersing solvent, 500 μL of ethanol; extraction solvent, 150 μL of chloroform; chelating agent, 150 μL of 0.01% rac-(E,E)-N,N′-bis(2-chlorobenzylidene)cyclohexane-1,2-diamine; and sample volume, 15 mL. The method was validated using the certified reference material SPS-WW2 waste water. The method offered a limit of detection (LOD) of 2.6 μg/L, a limit of quantification (LOQ) of 8.5 μg/L, and a relative standard deviation (RSD) of 5.2%.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The accurate determination of lead is an important issue in analytical chemistry because of very low concentrations in some samples and matrix interference in real samples.

    “Therefore, the accurate determination of lead is an important issue in analytical chemistry because of the very low concentrations in some samples as well as the presence of a matrix in real samples, which may interfere with instrumental determination [15,16,17].”

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.
