Determination of Pentachlorophenol in Drinking Water
Este trabalho relata um método envolvendo derivação in situ e extração para determinação de resíduos de PCP em amostras de água. O derivado acetilado de PCP é analisado por cromatografia a gás com detector por captura de elétrons. O limite de detecção do método é de 1 μg/L e sua eficiência é demonstrada pelos valores médios de recuperação (78-108%) estudados em três níveis de fortificação (2; 1...
متن کاملGRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY WITH MAlIlRIX MODIFICATION FOR DETERMINATION OF LEAD IN DRINKING WATER
An amoniumvanadate plus sodium molybdate mixed modifier Graphite Furnace Atomic Absorption Spectrometric method has been developed for determination of traces of lead in drinking water. The concentration of lead in the sample is obtained by direct comparison to linear working graph prepared from aqueous standards in the modifier medium, The results indicate the better performance of the pro...
متن کاملdetermination of fluoride in sanandaj drinking water resources
fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...
متن کاملDetermination of Hexavalent Chromium in Drinking Water Using Ion Chromatography
INTRODUCTION Hexavalent chromium, Cr(VI), is the most toxic form of the metal chromium, a primary drinking water contaminant in the U.S. Dissolved hexavalent chromium can be determined as chromate (CrO 4 ) by ion chromatography in drinking water, groundwater, and industrial wastewater effluents as described in U.S. EPA Method 218.6 and Dionex Technical Note 26. Dionex Technical Note 26 uses a 2...
متن کاملElectrochemical Determination of Pentachlorophenol in Water on a Multi-Wall Carbon Nanotubes-Epoxy Composite Electrode
The aim of this study was the preparation, characterization, and application of a multi-wall carbon nanotubes-epoxy composite electrode (MWCNT-EP) with 25%, wt. MWCNTs loading for the voltammetric/amperometric determination of pentachlorophenol (PCP) in aqueous solutions. The structural and morphological aspects of the MWCNT-EP composite electrode were examined by scanning electron microscopy. ...
