Table 2 The performance of electrochemical detection methods was compared for the determination of organophosphorus pesticides.
Scanning method | Scanning peak | Modification method | Accumulation/adsorption time | Linear range (ng·mL−1) | Detection limit (ng·mL−1) | Comments | Reference |
|---|---|---|---|---|---|---|---|
DPV | Pc | Acetylene black-chitosan composite film | 30 s | 5.26–26 320 | 0.5 | Short accumulation time, more active sites, high sensitivity. | |
SWV | Pa | Molecularly imprinted sol-gel film | 80 s | 2.63–2632 | 2.34 | Fast response, low detection limit, wide linear range, high selectivity and sensitivity | |
SWV | Pa | Au-ZrO2-SiO2 nanocomposite spheres | 5 min | 1–500 | 0.5 | Fast, sensitive, and selective. | |
SWV | Pa | Gold/sodium dodecyl-benzene- sulfonate nanoparticles | 120 s | 131.61–26 321 | 22.64 | Simple and convenient compared with self-assembled monolayers; easier and more controllable than common electrode modification techniques. | |
SWV | Pc and Pa | Graphene oxide dispersion | 120 s + 240 s | 1–400 | 0.1 | Modification procedure is simple and convenient, electrical signal is enhanced, high sensitivity potential application prospect. | This study |
