AI Article Synopsis

  • A new quick testing method for persistent organic pollutants (POPs) has been developed using paper spray ionization with carbon nanotubes, in combination with a small ion trap mass spectrometer.
  • The method is efficient, allowing for analysis in under one minute while providing high accuracy with correlation coefficients over 0.99 and good recovery rates between 93.1%-105.8%.
  • The results suggest this technique is a strong candidate for immediate on-site detection of harmful pollutants in the environment.

Article Abstract

Rationale: Rapid on-site detection of persistent organic pollutants (POP) is highly desirable for environmental protection.

Methods: Herein, a rapid on-site analytical workflow was developed for the investigation of polycyclic aromatic hydrocarbons and perfluorinated compounds using multiwalled carbon nanotube-modified paper spray ionization (PSI) coupled with a miniature ion trap mass spectrometer. Critical parameters regarding PSI and miniature mass spectrometry analysis were optimized.

Results: The analytical performance of the developed method was evaluated under optimized conditions, obtaining a short analysis duration of less than 1 min, sufficient linearity with correlation coefficients greater than 0.99, acceptable recovery rates of 93.1%-105.8% with relative standard deviations of between 3.5% and 10.3%, and reasonable sensitivity with limits of detection and quantitation of 2-200 and 5-500 μg/L, respectively.

Conclusions: Considering these aspects, it was concluded that the present approach demonstrated a promising solution for rapid on-site detection of emerging POPs.
