This article presents research on the possibility of obtaining a hardened surface layer via nitriding in coupled plasma (ICP) for HS6-5-2 steel. The subject investigation was influence process parameters properties obtained layers. layers were characterized using an optical microscope, SEM (Scanning Electron Microscope), EDS (Energy Dispersive Spectroscopy), XRD (X-Ray Diffraction), and microha...

A few studies have reported the occurrence of monoethylmercury (CH(3)CH(2)Hg(+)) in the natural environment, but further verification is needed due to the lack of direct evidence and/or uncertainty in analytical procedures. Various analytical techniques were employed to verify the occurrence of CH(3)CH(2)Hg(+) in soil of the Florida Everglades. The identity of CH(3)CH(2)Hg(+) in Everglades soil...

The orthogonal method can be used to predict the optimum instrumental conditions and to guide the optimizing operations. This simplifies the ICP-MS optimization. In general, the final optimum parameter combination used in an analysis can be obtained after fine adjustments of the preferred parameters derived from the orthogonal experiment. This method can also be used to study the relationship b...
