A rapid, selective, sensitive and accurate method based on superparamagnetic molecularly imprinted polymer nanoparticles (MMIPNPs) was developed for the determination of tramadol (TRA) in human urine samples. The MMIPNPs were prepared by coating SiO2–Fe3O4 nanoparticles with polyaminoimide homopolymer and TRA as the template. The prepared MMIPNPs adsorbent was characterized by TEM, FT-IR, XRD and...
In this study, magnetite nanoparticles-modified low-cost activated carbon (MMAC) was used as an adsorbent for the removal of the anionic and cationic dyes Congo red, reactive blue 19, thionine, janus green B, methylthymol blue and mordant Blue 29, from aqueous solutions. Batch studies were performed to address various experimental parameters like pH, contact time, temperature and adsorbent dosage...
