摘要:Abstract(#br)In the analysis of arsenic (As) with ICP-MS, it was observed that methanol addition to the sample decreases the amount of 40 Ar 35 Cl + formed in the previous study. To investigate the effect of methanol addition on generation of isobaric polyatomic ions and its mech...

摘要:Abstract(#br)Potential ways to avoid limitations and improve analytical sensitivity in the determination of fluorine (F) in solid materials using wavelength dispersive X-ray fluorescence (WDXRF) spectrometry were investigated. Chemical shift was not significant in the F dete...

摘要:Abstract(#br)Current risk characterization in ecological risk assessment does not consider bioavailability of heavy metals, which highly depends on physicochemical properties of environmental media. This study was set to investigate the effect of humic acid (HA), used as a s...
