Abstract
Summary: Different polarographic and voltammetric techniques for the determination of molybdenum at the trace level have been investigated. As a result, a new high-sensitivity procedure for the determination of molybdenum by adsorptive stripping voltammetry was developed. The method is based on the reaction of molybdenum(VI) with 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone (chloranilic acid) to produce a complex which is absorbed onto mercury at −0.20 V (vs. Ag/AgCl, 3 mol/l KCl) from pH 2.7 solution. The cathodic stripping peak at −0.62 V can be used to determine molybdenum with a detection limit of 0.02 ng/ml after 5 min deposition time. The relative standard deviation for the determination of 0.1 ng/ml Mo after 5 min stirred collection was 6.6%. Interference from various inorganic ions and organic substances are reported. The method was applied to the determination of molybdenum traces in waters; interfering organic substances in polluted waters were destroyed by oxidative digestion in a microwave oven.

As a result, a new high-sensitivity procedure for the determination of molybdenum by adsorptive stripping voltammetry was developed. The method is based on the reaction of molybdenum(VI) with 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone (chloranilic acid) to produce a complex which is absorbed onto mercury at −0.20 V (vs. Ag/AgCl, 3 mol/l KCl) from pH 2.7 solution. The cathodic stripping peak at −0.62 V can be used to determine molybdenum with a detection limit of 0.02 ng/ml after 5 min deposition time. The relative standard deviation for the determination of 0.1 ng/ml Mo after 5 min stirred collection was 6.6%. Interference from various inorganic ions and organic substances are reported. The method was applied to the determination of molybdenum traces in waters; interfering organic substances in polluted waters were destroyed by oxidative digestion in a microwave oven.</abstract><note>Original Papers/Environmental Analysis</note><relatedItem type="host"><titleInfo><title>Fresenius' Journal of Analytical Chemistry</title></titleInfo><titleInfo type="abbreviated"><title>Fresenius J Anal Chem</title></titleInfo><genre type="journal" displayLabel="Archive Journal"></genre><originInfo><dateIssued encoding="w3cdtf">1992-01-01</dateIssued><copyrightDate encoding="w3cdtf">1992</copyrightDate></originInfo><subject><genre>Chemistry</genre><topic>Analytical Chemistry</topic><topic>Food Science</topic><topic>Inorganic Chemistry</topic><topic>Physical Chemistry</topic><topic>Monitoring/Environmental Analysis/Environmental Ecotoxicology</topic></subject><identifier type="ISSN">0937-0633</identifier><identifier type="eISSN">1432-1130</identifier><identifier type="JournalID">216</identifier><identifier type="IssueArticleCount">49</identifier><identifier type="VolumeIssueCount">12</identifier><part><date>1992</date><detail type="volume"><number>342</number><caption>vol.</caption></detail><detail type="issue"><number>1-2</number><caption>no.</caption></detail><extent unit="pages"><start>186</start><end>190</end></extent></part><recordInfo><recordOrigin>Springer-Verlag, 1992</recordOrigin></recordInfo></relatedItem><identifier type="istex">5B786F5D31F50747639127B6DC526E9BAD24720A</identifier><identifier type="DOI">10.1007/BF00321720</identifier><identifier type="ArticleID">BF00321720</identifier><identifier type="ArticleID">Art41</identifier><accessCondition type="use and reproduction" contentType="copyright">Springer-Verlag, 1992</accessCondition><recordInfo><recordContentSource>SPRINGER</recordContentSource><recordOrigin>Springer-Verlag, 1992</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
