Fast SPE and HPLC–DAD determination of brucine in human urine using multi-walled carbon nanotubes modified with magnetic nanoparticles
A nanomaterial comprising Fe 3 O 4 -modified hydroxylated multi-walled carbon nanotubes (Fe 3 O 4 –MWCNTs–OH) was prepared by a co-precipitation method. Combined with HPLC-photodiode array detector (DAD), Fe 3 O 4 –MWCNTs–OH was used to determine brucine in human urine. Some important parameters tha...
