Magnetic dispersive solid-phase extraction of organochlorine pesticides from honey samples in a narrow-bore tube prior to HPLC analysis.

ABSTRACT: The evaluation of pollutant residues, particularly pesticides, in honey samples is of utmost importance to maintain human safety. In this study, a magnetic dispersive solid-phase extraction method within a narrow-bore tube was introduced for the extraction and preconcentration of four organochlorine pesticides (OCPs) from honey samples. For this purpose, 40 mg of the synthesized magnetic Ni-MOF-I sorbent dispersed into 1 mL of acetonitrile was injected into the sample solution filled in a narrow-bore tube. An external magnet was placed near the end of the tube to collect the sorbent. After 5 min, the stopcock connected to the tube was opened, allowing the sample solution to pass through the sorbent held by the magnet at a flow rate of 5 mL min^-1. The sorbent was then eluted usin
