Abstract

A novel retrievable bifunctional magnetic nano-structure (sodium dichloroisocyanurate immobilized on the Fe3O4@SiO2@Si(CH2)3Cl surface) was synthesized. Its antibacterial performance as water disinfectant successfully evaluated. The value of Minimum Bactericidal Concentration (625 ppm) and Minimum Inhibitory Concentration (314.5 ppm) show that magnetic nano-structure is a very effective antibacterial structure against the E. coli bacteria. In addition the viability of bacteria (%) was evaluated at different contact time against magnetic nano-structure. The disinfection procedure is very clean without any residual cyanuric acid in water. In other hand, oxidizing performance of nano-structure against the azo dye (acid red-18) was evaluated which attributed to the releasing HOCl in water. Kinetic of dye removal was measured at 0.01, 0.05, 0.1, and 0.5 g of nano-structure. Reducing pH and increasing temperature leads to increased Acid Red 18 degradation. Chemical oxygen demand (COD) measurement shows the effectiveness of nano-structure in acid red-18 degradation. The nano-structure turns to be magnetically retrievable, clean disinfectant, wastewater treatment agent, and its chlorine can be regenerated simply by exposure to household bleach such as Ca(OCl)2.

  • HOCl/OCl− remains the preferred active microbicidal agent in pool disinfection.

    “In recent years, the use of sodium dichloroisocyanurate as an organic precursor to HOCl has emerged, but HOCl/OCl− remains the preferred active microbicidal agent [166].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
