Simultaneous determination of 11 antiseptic ingredients in surface water based on polypyrrole decorated magnetic nanoparticles

Abstract

Polypyrrole decorated magnetic nanoparticles Fe3O4@PPy were synthesized by a simple and efficient chemical oxidative polymerization method and used for the extraction of 11 antiseptic ingredients in surface water.

Impact of the COVID-19 pandemic on household disinfectant consumption behaviors and related environmental concerns: A questionnaire-based survey in China

“…What’s worse, anxiety and fear in the public triggered by COVID-19 have caused panic buying in an attempt to stockpile and hoard the household disinfectant products [19] . It has been estimated that at least 2000 tons of disinfectants have been dispensed in Wuhan City alone [36] , where the first cases of COVID-19 syndrome with unknown origin were identified in early December 2019 [5] . Even fleets of trucks, mini-tankers and drones etc.…”

“…Other toxic disinfection by-products such as chloramine or N-nitrosodimethylamine, that were formed from the combination of disinfectants and nitrogen, have been classified as carcinogens. In addition, chlorine released from disinfectants can directly destroy the cell walls or damage proteins of organisms by oxidation [17] , [36] . A dose-response genotoxic effect has been demonstrated in the earthworm Eisenia andrei Bouché ( Lumbricidae ) coelomic fluid shelters leucocytes (coelomocytes) following exposure to 15-120 µM hydrogen peroxide [15] .…”

“…In addition, disinfectant residues in the environment would “wipe” several commensals in various niches, and induce immeasurable collateral damage to microbial diversity [22] . Considering these potential hazardous effects of disinfectant residues on environment, organisms and biodiversity, the tremendous rise in use of disinfectants during COVID-19 pandemic has been considered highly likely to cause worldwide secondary disasters in ecosystems and human health, which have elicited heightened concerns from scientists [19] , [36] .…”

Rapid Determination of Vitamin D3 in Aquatic Products by Polypyrrole-Coated Magnetic Nanoparticles Extraction Coupled with High-Performance Liquid Chromatography Detection

“…Fe 3 O 4 NPs were coated by polymerization of pyrrole (PPy) using the method of Zhang et al (2020) [ 23 ] with few modifications. In brief, 0.028 g of sodium dodecyl sulfate and 0.2 g of Fe 3 O 4 were added to 80 mL of deionized water and sonicated for 20 min to obtain a homogeneous dispersion.…”

“…PPy has been used on Fe 3 O 4 nanoparticles to form an adhesive coat with more binding sites for target molecules by means of π-π stacking, hydrogen bonding, van der Waals forces, and charge interactions [ 20 ]. Fabricated Fe 3 O 4 @PPy composites have been successfully utilized for the removal of Ni (II) and Cr (VI) from industrial effluent [ 21 ] and rapid extraction of antiseptic ingredients or estrogens before HPLC-MS/MS determination [ 22 , 23 ]. In a recent study, Jiao, Zhang and Fan (2016) [ 10 ] described the effective extraction capacity of Fe 3 O 4 @PPy for vitamin D 2 and vitamin D 3 in the milk matrix.…”
