This paper describes an experimental study on the effects of polyaluminium chloride (PAC) pH, turbidity, and electrical properties pool water. Our results demonstrates that as concentration PAC increases, pH decreases until a 2.5 mg/L, suggesting acidic effect flocculant. Thus, turbidity with increasing up to indicating effective particle clumping settling. Beyond this concentration, starts increase, possibly due excessive flocculant dosage or unintended reactions. Impedance spectroscopy is used analyze treated The Nyquist Bode plots reveal two relaxation processes changes in conductivity. optimal for treating water found be where suspended particles are effectively removed while maintaining suitable Also, equivalent circuit devlopped model behavior, its simulation closely matches data. times DC conductivity influenced by different behaviors observed below above mg/L. Below neutralizes particles, it, excess content leads increases these parameters.

There are various methods for environmental organic pollutant degradation and removal, among which ultraviolet/persulfate has drawn significant attention due to its excellent oxidizing properties, high maneuverability, less formation of by-products. To comprehensively assess the development ultraviolet/persulfate, a bibliometric analysis was conducted based on relevant literature indexed by Web Science from 2002 2024. The findings revealed growing number publications, with China, Iran, United States being top three countries highest total publications. Robust regional collaborations were evident. Additionally, Chinese American scholars presented more activity in this field, their publications exhibited higher quality. Furthermore, current research hotspots, as indicated keywords, primarily focused mechanism reaction kinetic model simulation. Bibliometric results underscored that an effective environmentally friendly disinfection technology, possessed substantial potential controlling diverse pollutants, such antibiotics, dyes, natural substances, heavy metals, microorganisms, so on. Future might concentrate developing new catalytic composites optimization photoactivation system. practical application still needs be investigated complexity water matrix. revival microorganisms variation toxicity should considered further.
