For the first time, jute activated carbon (JAC) derived from jute stick, a byproduct of the jute industry, was
characterised and evaluated for its cleanup efficiency in a mixture of 181 multiclass pesticide residue testing
using gas chromatography tandem mass spectrometry (GC-MS/MS). Four commercially-important food matrices
including okra, spinach, pomegranate and tea were chosen. Various physico-chemical techniques were used to
characterise the material. The cleanup method involved dispersive solid phase extraction (dSPE) using a combination
of JAC (5 mg) with 25 mg of primary secondary amine per mL of the sample extract (in ethyl acetate).
The findings demonstrated a lower matrix effect and higher signal-to-noise ratio were recorded for JAC. Overall,
the method offered satisfactory recoveries for most of the pesticides in all the tested matrices. The cleanup
effectiveness of JAC showed superiority over the commercially available, non-renewable dSPE sorbent viz.
graphitised carbon black (GCB). With a production cost of only US Dollar ~10/kg, JAC is a low-cost alternative
to commercial GCB (cost = US Dollar 11–12/g). The study valorises the potential of JAC and anticipates its largescale
application in food testing laboratories.
