Abstract:
Polyethylene (PE) is the polymer that is used in almost all pipe-manufacturing industries. After that, it is often disposed of in nearby water bodies, causing water pollution. PE has a severe impact on human and environmental health even at low concentrations. It also significantly affects the aquatic environment. The electro catalysis method has shown high efficiency in degrading a variety of organic substances in wastewater. In the present study, NiMoMn, Ni Mn, Ni Mo Ba, and Ni Mo were developed as working electrodes to remove PE in wastewater. The samples were collected from the I-9 industrial area (Akbar & Zikria (Pvt) ltd) and analyzed for physicochemical properties and organic constituents, including concentration of PE. This study examined the electrochemical removal of polyethylene utilizing nickel-based aerogels and nano catalysts. The performance of synthesized materials towards the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) was evaluated using linear sweep voltammetry (LSV), cyclic voltammetry (CV), and Chrono potentiometry were used to test electro-oxidation and catalytic efficiency. The experiment was conducted in both acidic (H2SO4) and alkaline medium (KOH)with different scan rates and different polyethylene concentrations of 25 ppm, 50ppm, and 75 ppm. The process was monitored using a three-electrode system ,i.e., reference, counter, and working electrode, equipped with a potentio stat. The results showed the 92% removal by Ni Mo Mn aerogel, while the Ni Mo nano catalyst shows maximum degradation to 94.95% of PE in synthetic wastewater. All the electrode materials remain stable for an 8 h experiment of Chrono potentiometry, showing that the novel material has good electrochemical degradation and can be used for large-scale medium.
