Among devices, filters based on dielectric fibers stand out, which capture precharged aerosol particles in the filtered air flow. In this study, we demonstrate the influence of the configuration of the grounding electrode located in the filter for removing excess charge to ensure safe filter operation on the filter efficiency in capturing NiO aerosol particles. This study proposes a method for measuring the total charge and local potential of dielectric polypropylene fiber filters. It has been shown that placing the grounding electrode closer to the outer surface results in significant potential non-uniformity, with the potentials between the electrode turns being approximately three times higher than those above the turns. This disparity directs charged particles toward low-potential zones, reducing overall efficiency. Conversely, shortening the electrode and embedding it deeper promotes uniform surface potential and maximizes total charge, which provide the lowest penetration rates for NiO particles (0.23 and 0.14%). Additionally, a proposed model of the filter electrical properties, in which each filter section is considered as a resistor, explains charge and current distribution. Finally, we discuss capture mechanisms and the contribution of each to the overall filter efficiency.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"99 6","pages":"299 - 315"},"PeriodicalIF":0.7,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148314744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the corrosion potentials (Ecorr) of AA 5052 in Na2SO4 and H3BO3 electrolytes are similar and higher than that of AA 5052 in NaCl electrolyte. Depending on the potential and chemical composition of the electrolyte (presence or absence of H2BO3–, Cl–, and SO42– anions), passivation and different types of corrosion (pitting, uniform, and partial corrosion) occurred for AA 5052. In Na2SO4 and H3BO3 electrolytes, AA 5052 exhibits acceptable passivation behavior: the passivation current density (ipass) is low, and the passivation potential range (ΔEpass) is extended. However, in NaCl electrolyte, the passive layer is not very stable: ipass is high, and ΔEpass is limited. Additionally, the stability of the passive layer decreases with increasing NaCl concentration.

Based on single-factor experimental results, the response surface methodology (RSM) was used to optimize the PET glycolysis process in a multivariate way, and a mathematical model was established by combining with the Design–Expert software to quantify the interactions of the parameters of reaction temperature (199℃), time (3.8 h), ethylene glycol dosage (16 mL), and catalyst dosage (0.39%) to achieve a breakthrough improvement of BHET yield of A breakthrough improvement of 83.53% was achieved.
