Determination of molybdenum in steel samples by ICP-AES after separation and preconcentration using nanometre-sized titanium dioxide
A sensitive and selective method has been developed for the determination of Mo in steel samples using a nanometre-sized titanium dioxide micro-column (20 mm 6 3.0 mm id) and inductively coupled plasma atomic emission spectrometry (ICP-AES). Under the optimized conditions (pH 1.0, flow rate 1.5 mL min), Mo was retained on the column and separated from the iron matrix, then eluted with 0.5 mol L...
متن کاملMultielement determination and speciation of major-to-trace elements in black tea leaves by ICP-AES and ICP-MS with the aid of size exclusion chromatography.
A multielement determination of major-to-trace elements in black tea leaves and their tea infusions was carried out by ICP-AES (inductively coupled plasma atomic emission spectrometry) and ICP-MS (inductively coupled plasma mass spectrometry). Tea infusions were prepared as usual tea beverage by brewing black tea leaves in boiling water for 5 min. About 40 elements in tea leaves and tea infusio...
متن کاملDetermination of Trace Metals in Human Urine Using the NexION 300/350 ICP-MS
The monitoring of trace metals in human urine plays an important role in research. Traditionally, urine analysis has been accomplished by graphite furnace atomic absorption (GFAA). However, when large numbers of samples are analyzed for multiple elements, GFAA becomes very cumbersome and restrictive, since it can only determine one element at a time. Additionally, the detection capability of IC...
متن کاملDetermination of Trace Metals in Human Urine Using the NexION 300 ICP-MS
This application note describes the use of an innovative, nextgeneration inductively coupled plasma-mass spectrometer (ICP-MS) for the determination of trace elements in human urine. The study will show how spectral interferences are overcome with the instrument’s breakthrough Universal Cell TechnologyTM, and how the unique interface and ion-filtering design is ideally-suited for the analysis o...
متن کاملOn-line preconcentration method for the determination of trace metals in water samples using a fully automated pretreatment system coupled with ICP-AES.
An automated on-line sample-preparation method using a computer-controlled pretreatment system (Auto-Pret AES system) coupled with ICP-AES was developed. In this work, an iminodiacetate chelating resin, packed in a mini-column and installed in the system was employed for the collection/concentration of 13 trace metals, including such toxic metals as Be, Cd, Cr, Cu and Pb. The limits of detectio...
