This study presents the development and validation of an analytical method using a magnetic sorption phase anchored with zeolites for cannabinoid extraction from urine samples of patients suspected of Cannabis sativa intoxication. High-performance liquid chromatography coupled with a diode array detector (HPLC-DAD) was employed for the identification and quantification of tetrahydrocannabinol (THC) and cannabidiol (CBD). Magnetic nanoparticles (MNPs) were synthesized using the coprecipitation method and anchored to zeolite, which was identified as the optimal natural sorbent phase. MNPs anchored with zeolites (MNPs@ZEO) were characterized using X-ray diffractometry, scanning and transmission electron microscopy, Fourier transform infrared spectroscopy (FT-IR), zeta potential, and particle size analysis. Multifactorial planning was conducted to optimize the dispersive magnetic solid-phase extraction (DMSPE) technique with MNPs@ZEO, with the best experimental condition being 15 mg of MNP
“This is a development worth tracking. The clinical implications will become clearer as more evidence accumulates.”

FAQ
What was this zeolite nanoparticle method developed to do?
It is an analytical method for extracting cannabinoids from urine samples of patients suspected of Cannabis sativa intoxication. The study describes both its development and its validation, using a magnetic sorption phase anchored with zeolites as the extraction material.
Which cannabinoids does this urine analysis method measure, and how?
The method identifies and quantifies tetrahydrocannabinol (THC) and cannabidiol (CBD). After the cannabinoids are extracted from urine, they are analyzed using high-performance liquid chromatography coupled with a diode array detector, known as HPLC-DAD.
How were the zeolite-anchored magnetic nanoparticles made?
The magnetic nanoparticles were synthesized using the coprecipitation method and then anchored to zeolite, which the researchers identified as the optimal natural sorbent phase. The resulting material is referred to as MNPs@ZEO, meaning magnetic nanoparticles anchored with zeolites.
How was the new extraction material tested and optimized?
The MNPs@ZEO material was characterized with X-ray diffractometry, scanning and transmission electron microscopy, Fourier transform infrared spectroscopy (FT-IR), zeta potential, and particle size analysis. The researchers then used multifactorial planning to optimize a dispersive magnetic solid-phase extraction (DMSPE) technique with this material.
