Magnetic solid phase extraction of trace paracetamol and caffeine in synthetic urine and wastewater samples by a using core shell hybrid material consisting of graphene oxide/multiwalled carbon nanotube/Fe3O4/SiO2
Ulusoy, Halil Ibrahim; Yilmaz, Erkan; Soylak, Mustafa (ELSEVIER SCIENCE BV, 2019)A new hybrid material was synthesized including magnetic graphene oxide/multiwalled carbon nanotube core shell (GO/MWCNT/Fe3O4/SiO2) and used as magnetic solid phase extraction adsorbent for separation and pre concentration ... -
A new magnetic nanodiamond/graphene oxide hybrid (Fe3O4@ND@GO) material for pre-concentration and sensitive determination of sildenafil in alleged herbal aphrodisiacs by HPLC-DAD system
Yilmaz, Erkan; Ulusoy, Halil Ibrahim; Demir, Ozge; Soylak, Mustafa (ELSEVIER SCIENCE BV, 2018)A sensitive analytical methodology was investigated to concentrate and determine of sildenafil citrate (SLC) present at trace level in herbal supplementary products. The proposed method is based on simple and sensitive ... -
