cobalt is one of the most important constituent present in ceramic industries. glazers are the relevant workers when they are producing blue colored ceramic, causing occupational exposure to such metal. through this study, urinary cobalt was determined in glazers in a ceramic industry when they were producing blue-colored ceramic glazes.in this case-control study, spot urine samples were collec...

more than 30 mineral elements have been found with different key functions in helping plants and animals to survive and live healthy. as a direct result, they have always attracted the attention of scientists. the quest is to find some efficient analytical and quantitative procedures in this study to determine some mineral and trace elements of iranian crocus sativus l. corms. several studies h...

the combinations of inductively coupled plasma-optical emission spectrometry (icp-oes) and three classification algorithms, i.e., partial least squares discriminant analysis (pls-da), least squares support vector machine (ls-svm) and soft independent modeling of class analogies (simca), for discriminating different brands of iranian bottled mineral waters, were explored. icp-oes was used for th...

introduction: this study was carried out to determine elements (li, na, k, mg, ca, ba, b, al, si, v, cr, mn, fe, co, ni, cu, zn, se, ag and p) in the suaeda vermiculata (s. vermiculata) and suaeda aegyptiaca (s. aegyptiaca) in three different regions of southern iran using inductively coupled plasma optical emission spectrometry (icp-oes) after microwave-assisted acid digestion. materials and m...

background and purpose: determination of heavy metals in oils is necessary to establish quality standards on a country level. this study aimed to determine of heavy metal contents (cr, ni, as, cd, hg, pb, sb, sn, sr, al) in 12 seed oil samples in iran by inductively coupled plasma-optical emission spectrometry (icp-oes). materials and methods: the concentrations of heavy metal were determined b...

Inductively coupled plasma mass spectrometry is a powerful tool for the investigation of many materials. The Agilent 7500c with Octopole Reaction System was used to analyze major, minor and trace elements in two standard reference plant materials. The data obtained using the 7500c is compared to the certificate reference values and to results that were generated using inductively coupled plasma...

manganese zinc ferrite nanoparticles (mzf nps) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. to improve the colloidal stability of mzf nps for biomedical applications, nps were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (tpp) as crosslinker. the synthesized nps were characterized by x ray diffraction (xrd) analy...

a simple and rapid method for the determination of 137ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (icp-oes) coupled with least-squares support vector machine regression (ls-svm) is reported. by evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination of 137ba a...
