Design of a fiberglass-coated thin-film solid-phase microextraction patch for eco-friendly and efficient detection of carbofuran pesticides in bananas
Ankita Das, S. Balaji, Chiranjit Ghosh
TL;DR
A new eco-friendly method using a fiberglass-coated patch efficiently detects carbofuran pesticide in bananas.
Contribution
A novel fiberglass-based thin-film solid-phase microextraction patch is developed for trace-level pesticide detection.
Findings
The TF-SPME patch efficiently captures carbofuran at trace levels with a linear range of 100–2000 ng mL−1.
The method achieved a detection limit of 0.016 mg kg−1 using GC-MS/MS and a determination coefficient above 0.99.
The technique aligns with Green Analytical Chemistry principles by minimizing solvent use and waste.
Abstract
Carbofuran is a well-known insecticide that is widely used in farming practices to improve crop quality and shelf life. Due to its potential pesticidal activity, it is widely used in banana cultivation to protect the crop from various pests and fungal diseases. However, excessive use of this pesticide may lead to accumulation in banana fruits and subsequent transfer to the human body through the consumption of contaminated products. To quickly quantify the carbofuran in bananas, a fiberglass-based thin-film solid-phase microextraction (TF-SPME) patch was developed utilizing polydimethylsiloxane and divinylbenzene polymer particles. The results confirmed the efficiency of laboratory-designed TF-SPME analytical tools for capturing carbofuran residue at trace levels. In this study, the linear range covered 100–2000 ng mL−1. The limits of detection (LOD) for this method were estimated to be…
