This study outlines a straightforward method for preparing polyaniline/ sulfation carboxymethyl cellulose /multi carbon nanotubes PANI/S-CMC/MWCNTs nanocomposite that is both cost-effective and environmentally beneficial. Using as-prepared PANI/S-CMC/MWCNTs nanocomposites, a modified glassy carbon electrode (GCE/ PANI/S-CMC/MWCNTs) was produced to accomplish very sensitive electrochemical detection of 2-nitrophenol (2-NP). To investigate the morphology and structure of the nanocomposite, researchers used X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and Fourier-transform infrared spectroscopy, showing that the nanocomposite has excellent electrochemical performance. In the case of 2-NP, the differential pulse voltammetry experiment found that in the range of 2 to 80 µM (R2 = 0.934), there is a linear association between peak currents and concentrations. For 2-NP, the computed detection limit (S/N = 3) is 0.33 M, and limit of quantification for 2-NP is1.1µ M Furthermore, after correctly determining the target analytes in several water samples, the new sensor manifested a remarkable high recovery rate.

“…Besides, many active groups disclosed and positively charged functionalized networked porous structure of zein formed in acidic condition [25][26]. The microholes, functionalized porous structures, and different functional groups produce synergetic properties towards absorption [23,27]. This property is essential to support the adsorption of dye pollutants to the heterogeneous catalyst surface.…”

Fabricating a stable, recyclable, and eco-friendly photocatalyst for dye treatment is vital in sustaining a clean ecosystem. In this regard, polyaniline/TiO2 (PANI/TiO2) photocatalyst was immobilized by zein/hydroxyethyl cellulose (zein/HEC) adhesive to enhance recyclability and catalytic activity. The blending of zein/HEC/PANI/TiO2 photocatalyst involves insitu oxidative polymerization, followed by immobilization with zein/HEC functionalized composites. The PANI/TiO2 composite was successfully grafted with the adhesive through physicochemical interaction, as evidenced by field emission scanning electron microscope (FESEM), Fourier transform infrared spectroscopy (FTIR), and Powder X-ray diffractometer (XRD). The simultaneous thermal analysis (STA) results show that the photocatalyst has the best thermal stability relative to PANI and PANI/TiO2 in the recommended range of dye degradation temperature. The effect of external factors like TiO2 nanoparticle proportion, pH of the solution, and catalyst dosage was studied in response to dye degradation capacity. The synthesized catalyst is efficient to degrade methyl orange in a wide range of pH. The kinetics of the catalysis reaction obeys first order kinetics. The maximum degradation efficiency achieved was 97.9 and 84.3% in the presence and absence of light, respectively. The catalyst was easily recovered by decantation, and its catalytic efficacy was more than 94% after five cycles. Hence, it is a promising alternative for decolorizing anionic dyes from wastewater.
