“…A nickel-cobalt layered double hydroxide (NiCo-LDH) supported on green organic-inorganic nanohybrid (rGO-CuO) was drop cast on a gold electrode (AuE). Electrochemical measurements showed good conductivity and large active surface area favoring the electrochemical redox reaction of PCP with a linear range of 1-50 μM and LOD was estimated to be 12.64 nM (Meskher et al 2023). (Zhu et al 2020) created a sensor with an interface made of a hollow zeolitic imidazolate framework (ZIF)derived mesoporous carbon material (HZC/SPCE) that detects PCP without the use of enzymes, pre-concentration, or metals.…”

Pentachlorophenol (PCP) is a manmade chemical that is widely present in the environment and is mostly used as a wood preservative. Therefore, to conduct remediation studies, it is imperative to determine the most effective PCP analytical technique. PCP can be analyzed using a variety of analytical tools, including non-destructible methods like X-ray fluorescence spectrometry (XRF) and electrochemical sensors (EC), destructible tools like gas chromatography (GC), thin layer chromatography (TLC), colorimetry, ultraviolet–visible and infrared spectroscopy (UV–vis/IR), and high-performance liquid chromatography (HPLC). the colorimetric approach is less recommended because of its low sensitivity and precision, whereas TLC offers superior recovery rates and precision but is expensive, takes longer, and is unable to resolve complicated combinations. Higher recovery rates, sensitivity, precision, and superior separation are all offered by HPLC; however, its effectiveness is impacted by time, money, and solvent compatibility. The most favored destructible approach is GC because it is efficient in terms of both cost and time and offers superior precision and separation. Although XRF is frequently used in the wood industry to test PCP in treated wood and treating solutions, scientific research has avoided using it because of its high cost and ability to identify chemicals based only on their elemental composition—in the case of PCP, it is chloride. Among all methods, EC is shown to be more dependable than the other methods listed because it is extremely specialized, less expensive, and offers a faster response. It is possible to make more changes to the current analytical techniques, such as enhancing extraction techniques, creating a universal HPLC column, developing more affordable and high-precision EC electrodes, and evaluating a larger variety of samples from different matrices. This review has shed light on the many analytical tools available for determining PCP and the knowledge gaps in the field of study.

“…Thus, the simultaneous determination of HQ and CC in their mixture is not easy. To solve this problem and to separate the oxidation peaks of HQ and CC, various materials with high selectivity, good conductivity and high stability including graphene, [22][23][24] mesoporous silica, [25] mental oxide, [26] polymer, [27] Mxene, [28] MOF, [29,30] carbon nanotube, [31][32][33] and biomass-based carbons [34] have been employed as modifiers of electrode surface. The Biomass-based carbons were widely applied in electrochemical sensors including bagasse, [35] lotus stem, [20] kiwi skin, [36] and pig lung [37] to solve the issues of expensive material, tedious procedure and poor electrochemical performance.…”

Hemicellulose and lignin, which are main components of wood biomass with different structures, were carbonized and activated by KOH to prepare wood biomass‐derived porous carbons (WBM‐PCs). The resulting WBM‐PCs were characterized by SEM, XRD, Raman, FI‐IR, and N2‐adsorption/desorption isotherms, and successfully utilized as an effective modifier on the glassy carbon electrode surface (GCE) for simultaneous electrochemical determination of dihydroxybenzene isomers, i. e. hydroquinone (HQ) and catechol (CC), which are highly toxic and non‐degradable. The resulting WBM‐PCs‐modified GCEs allowed simultaneous determination of HQ and CC with cyclic voltammetry and constant‐potential amperometry. The linear range for determination of HQ by hemicellulose‐derived carbon (HC) was from 1.0 to 3000 μmol/L with the limit of detection (LOD) of 1.05 μmol/L, and that for CC was from 1.0 to 5000 μmol/L with LOD of 0.4 μmol/L. For lignin‐derived carbon (LC), the linear range for HQ was from 0.5 to 1000 μmol/L with LOD of 0.095 μmol/L, and that for CC was from 0.5 to 3000 μmol/L with LOD of 0.15 μmol/L. These results imply that wood biomass (hemicellulose and lignin), which is sustainable, renewable and environment‐friendly material, have potential as an effective precursor of electrochemically active porous carbon materials applicable to various electrochemical sensors.
