The use of slurry sampling for the determination of manganese and copper in various samples by electrothermal atomic absorption spectrometry

Selective determination of copper and iron in various food samples by the solid phase extraction

“…Overexposure to copper causes nausea, vomiting, diarrhea, hepatic neurosis, gastrointestinal bleeding, hypertension and dermatitis (Onianwa, Adeyemo, Idowu, & Ogabiela, 2001;Sarma, Kumar, Reddy, & Reddy, 2005). The average dietary intake of copper in the US is approximately 1.0-1.1 mg day À1 for adult women and 1.2-1.6 mg day À1 for adult men (Tokman, 2007). Iron is an integral part of many proteins and enzymes and is an essential component of proteins involved in oxygen transport, regulation of cell growth and differentiation.…”

Slurry analysis after lead collection on a sorbent and its determination by electrothermal atomic absorption spectrometry

“…In case of any problem during injection, the furnace programme was stopped and injection was repeated after thermally cleaning the tube. However, since the injections in previous studies were performed manually, above-mentioned problems were hardly occured [19]. In addition, the depth of the injection hole of graphite furnace used in this study is appropriate to the manual pipettings successfully which is not appropriate at recent instruments.…”

Slurry analysis of cadmium and copper collected on 11-mercaptoundecanoic acid modified TiO2 core-Au shell nanoparticles by flame atomic absorption spectrometry

“…The main problem with slurry technique is the preparation of a slurry staying homogeneous at least during the whole analysis which requires careful optimization of some experimental parameters such as particle size, slurry volume, effective mixing, the addition of dispersants, the ratio of solid matter to total slurry volume, etc. [22][23][24][25][26][27][28][29][30].…”
