Ultra-trace Determination of Palladium(II) by Spectrophotometric Flow Injection Analysis
Nowadays, palladium compounds due to their especial characteristics used in different industries, mainly in electrical power sources and chemical productions as a catalyst. Therefore, Pd concentration is increasing in our around that can be contaminant our environment due its toxic effects. In this work, a simple, selective and rapid flow injection method of analysis (FIA) has been developed fo...
متن کاملReference Methods in Ultra-trace Analysis of Milk Products
Based on experiences with international standardization of analytical methods for milk products are described the problems and solutions of collaboratively developing and testing reference and other standard methods for trace analysis of milk products. Contaminations from laboratory equipment, chemicals and air must be eliminated and interferences corrected. Precautions traditionally applied bu...
متن کاملUltra Trace Elements and Selenium
During the past decade there has been a large upsurge in interest in nutritionally essential trace elements. In the clinical field the recognition that deficiency can occur in human subjects in many practical dietary situations has been of crucial importance from the public health viewpoint worldwide. In this chapter we review briefly our knowledge of the ultra trace elements chromium, manganes...

متن کاملDetermination of ultra trace of thiosemicarbazide by adsorptive stripping voltammetric method
In the present work, an adsorptive stripping voltammetric method using a hanging mercurydrop electrode (HMDE) was described in order to determine the ultra trace of thiosemicarbazidein different real samples. The method is based on accumulation of thiosemicarbazide on mercuryelectrode. The potential was scanned to the negative direction and the differential pulse strippingvoltammograms were rec...
