Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni-Fe(PDC)/GR can quantify carbendazim in spiked strawberry and apple juice with satisfactory recoveries and low RSD values.
Caveat: Only spiked recovery tests are reported; non-spiked samples showed no DPV signal in the fixed potential window.
10 · 4. Conclusions · Table 2 · Linked to 3 structured results
The article reports inconsistent LOD values: 2.3 nM in the abstract but 3.2 nM in the DPV section, Table 1 and conclusion.
Caveat: The extraction marks 3.2 nM as best value because it is repeated in the detailed results and table.
1 and 8 · Abstract; 3.8. Differential pulse voltammetry study · Table 1 · Linked to 2 structured results
Anchoring the bimetallic Ni-Fe(PDC) MOF on conductive graphite lowers charge-transfer resistance relative to pure MOF and improves electrochemical charge-transfer kinetics.
Caveat: This is an electrode-level EIS comparison, not a four-probe intrinsic framework conductivity measurement.
8 · 3.7. Cyclic voltammetry study · Fig. 6c · Linked to 2 structured results
The high surface area, pore volume and mesoporous/microporous structure of the MOF-deposited graphite rod improve analyte adsorption and carbendazim detection.
Caveat: The link is argued from correlated morphology/porosity and sensing performance; no isolated kinetic adsorption experiment is reported.
4 · 3.4. Surface analysis · Fig. 1d,e · Linked to 5 structured results
Carbendazim redox reaction kinetics at the Ni-Fe(PDC)/GR sensor follow a diffusion-controlled mechanism.
Caveat: Based on linear peak-current dependence on square-root scan rate.
6 · 3.7. Cyclic voltammetry study · Fig. 4c · Linked to 1 structured result
The carbendazim oxidation reaction on Ni-Fe(PDC)/GR is assigned to a two-electron/two-proton process.
Caveat: Electron number is calculated from electrochemical equations and pH slope is near but not equal to the Nernst value.
