A NOVEL AND HIGHLY SENSITIVE CATALYTIC METHOD FOR THE DETERMINATION OF ULTRA TRACE AMOUNTS OF CERIUM WITH SPECTROPHOTOMETRIC DETECTION
Cerium (IV) has a catalytic effect on the very slow redox reaction between gallocyanine and bromate in acidic media. The reaction was monitored spectrophotometrically at 525 nm by a fixed time method of 4.0 rnin from initiation of the reaction. The decrease in absorbance at 525 nm is proportional to the Ce (IV) concentration in the range of 0.005-1.000 and 1.00-10.00 pg. ml-l. The limit of ...
متن کاملSynthesis and application of a novel magnetic nanocomposite for determination of trace Cd(II) in water samples
In this work for the first time, Fe3O4@SiO2 core-shell nanoparticles functionalized with isatin groups as a magnetic nanosorbent was applied for the simultaneous extraction of trace amounts of cadmium (II). The characterization of this nanosorbentwas studied using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The effect of seve...
متن کاملN-octyl-modified magnetite NPs for optimization of solid phase extraction for trace analysis of phenytoin in real samples
objective: Phenytoin is an anti-seizure medication used to treat epilepsy, as well as to control arrhythmias (irregular heartbeat) and to treat migraine headaches and nerve pain. It is recommended to determine the amount of this drug in the blood to control the seizure and prevent its toxicity. In the present study, a sensitive and simple procedure based on the dispersive solid phase extraction...

15 صفحه اولGlow Discharge Mass Spectrometry : Trace Element Determinations in Solid Samples
Glow discharge mass spectrometry (GDMS) is a mature, versatile technique for the direct determination of trace elements in a variety of materials. The technique is an extension of the earliest forms of mass spectrometry. Processes inherent to the glow discharge, namely cathodic sputtering coupled with Penning ionization, yield an ion population from which semi-quantitative results can be direct...
