“…The preparation of samples with a primary 1-naphthol solution concentration of 5 mg/L was done at pH values of 3, 5, 7, and 9. The samples were obtained and investigated at times of 0, 5,10,15,20,25,30,35,40,45, and 50 min on the catalyst's surface. To eliminate the effect of adsorption on removing 1-naphthol, all solutions were rotated for 45 minutes without the presence of light in the chamber.…”

Background:The 1-Naphthol, one of the derivatives of naphthalene, is the most significant industrial chemical that is widely used in the production of dyes, pharmaceuticals, and biochemical processes. Methods: In the present study, N, S-doped TiO2 thin film immobilized on silica sulfuric acid (SSA) glass microspheres (MS) was investigated as a novel high efficient photocatalyst. The N, S-doped TiO2 immobilized on SSA was fabricated using a simple modified sol–gel process. Its photocatalytic activities were then assessed using 1-naphthol solution in the presence of visible light. The physico-chemical properties of photocatalyst were characterized using energy-dispersive X-ray (EDX), scanning electron microscope (SEM) images and X-ray diffraction (XRD) pattern. Results: According to the obtained results, the optimal pH, time, concentration, and removal efficiency of 1-naphthol for N, S-doped TiO2 /SSA was 5, 50 minutes, 25mg/l and 92.12%. Conclusion:The present study confirms the usability of the immobilized N, S-doped TiO2 on SSA glass MS as a novel, effective, and efficient technique for treatment of wastewater containing 1-naphthol under visible light.

“…Trace levels of heavy metals in the environment can lead to the accumulation of this dangerous metal ion in internal organs and cause irreversible effects on human health (Abbaspour et al, 2013; Gashtasbi et al, 2017; Gashtasbi et al, 2018; Karimipour et al, 2021; Kazemi Noredinvand et al, 2016; Mehrdoost et al, 2022; Nikpour et al, 2020; Shokri et al, 2020; Tabari et al, 2021; Zangeneh et al, 2021). Mercury ions and organometallic species are known as highly toxic substances in nature and especially in water systems, and even small amounts of them can be very harmful to the health of living organisms (Cerdà et al, 2022; Elsherif et al, 2022).…”

The determination of inorganic mercury species in water, beverages and foods has been a special research priority in recent years because mercury, as a highly carcinogenic species, even in trace concentration, has high adverse effects on the body of living organisms. In this research, combining two extraction techniques, including microwave‐assisted cloud point extraction and dispersive‐solid phase extraction (MA‐CP‐dSPE), for the separation and pre‐concentration of mercury in environmental samples is presented. This method is based on the dispersion of nanoparticles in micellar media in the presence of a novel mono‐thiosemicarbazone Schiff base (2 N′‐[4‐diphenylamino]benzylidene) hydrazinecarbothiohydrazide) ligand. Using the experimental conditions defined in the optimization, the method allowed mercury determination from 0.020 to 350 mg/L with a detection limit of 0.005 mg/L. The accuracy of the procedure was tested by analysing certified reference material. The method was successfully applied to copper determination in spring water, beverage and rice samples.

“…However, prochloraz has strong biological toxicity including skin irritation, severe disruption of mammalian endocrine levels, etc. Overexposure can also cause serious mutagenic, carcinogenic, or teratogenic effects on mammals ( Zheng et al, 2015 ; Karimipour et al, 2021 ). In addition, the metabolic product of prochloraz is 2,4,6-trichlorophenol (TCP), which has significant pathological effects and potential carcinogenicity ( Li et al, 2010 ).…”

Convenient, and sensitive detection of pesticides and their metabolites in environmental or food samples is critical for assessing potential environmental and health risks. Here, a three-dimensional (3D) electrochemical sensing platform is proposed based on the integration of nanochannel array on pre-activated 3D graphene (p-3DG) electrodes with no need of additional adhesive layers, which enables sensitive detection of prochloraz and 2,4,6-trichlorophenol (TCP) in environmental and food samples. Through two-step electrochemical polarization, organic phase anodic oxidation, and aqueous phase cathodic reduction, p-3DG electrodes with high active area and excellent electrocatalytic performance were obtained. Vertically-ordered mesoporous silica-nanochannel film (VMSF) can be rapidly grown on the surface of p-3DG by an electrochemical-assisted self-assembly (EASA) method. Taking advantage of the high electrocatalytic activity of p-3DG and the ability of nanochannels to enrich TCP through hydrogen bonding, the VMSF/p-3DG sensor can sensitively detect TCP in the range of 10 nM to 0.1 μM and 0.1–15 μM with a low limit of detection (LOD) of 2.4 nM. Compared with p-3DG and VMSF-modified 2D electrodes, the fabricated sensor has a wide detection linear range and low LOD. The coexistence of model interferents such as protein, surfactant, and humic acid did not affect the electrochemical response of TCP, confirming the high anti-fouling ability of the VMSF/p-3DG sensor. In addition, prochloraz in vegetable and fruit samples was indirectly determined because TCP was the metabolite of prochloraz.
