Resumo: | Three analytical methods were developed for the determination of chlorine, iodine and mercury in solid and liquid samples, directly by high resolution continuum source atomic and molecular absorption spectrometry in graphite furnace. The first method objected the determination of chlorine in solid and slurry samples of different natures and chlorine contents (CRM 81002b human hair, SRM 1568b rice flour, ERM EC681 polyethylene, CRM BCR 460 coal, SRM 2692c bituminous coal, SRM 1575 sheet Of pine, CRM 686-1 iron oxide, SRM 1549 powdered milk) through the molecular formation of CaCl. The results were compared with those already available for the SrCl molecule and were superior, especially in samples with a high calcium content. The limit of detection and quantification obtained for the two molecular absorption lines of CaCl were 2.6 and 8.7 ng (620.862 nm) and 14.2 and 61.6 ng (377.501 nm), respectively. The iodine determination was performed through the formation of the SrI molecule in two samples of medicines containing iodine. The accuracy of the method was proved by comparative analysis by inductively coupled plasma mass spectrometry. The results obtained were higher compared to the existing BaI molecule that does not provide direct determination in solids. The limit of detection and quantification obtained were 0.035 and 0.117 μg, respectively. Finally, an analytical method for the determination of mercury in blood samples (SERONORM® LEVEL III and II) and urine (SERONORM®, Clincheck Control level I and II batch 432 and level II batch 923) were developed, directly, using gold nanoparticles. The method was compared to the existing method that uses potassium permanganate as oxidizing agent. The limit of detection and quantification obtained were 0.057 and 0.190 ng, respectively. |

O primeiro método objetivou a determinação de cloro em amostras sólidas e em suspensão de diferentes naturezas e teores de cloro (CRM 81002b cabelo humano, SRM 1568b farinha de arroz, ERM EC681 polietileno, CRM BCR 460 carvão, SRM 2692c carvão betuminoso, SRM 1575 folha de pinheiro, CRM 686-1 óxido de ferro, SEM 1549 leite em pó), através da formação molecular de CaCl. Os resultados foram comparados com os já existentes para a molécula de SrCl e mostraram-se superiores, especialmente em amostras com alto teor de cálcio. O limite de detecção e quantificação obtidos para as duas linhas de absorção molecular de CaCl foram de 2,6 e 8,7 ng (620,862 nm) e 14,2 e 61,6 ng (377,501 nm), respectivamente. Já a determinação de iodo realizou-se através da formação da molécula de SrI, em duas amostras de medicamentos contendo iodo. A exatidão do método foi comprovada através de analise comparativa por espectrometria de massas com plasma acoplado indutivamente. Os resultados obtidos se mostraram superiores em comparação com molécula já existente BaI que não proporciona a determinação direta em sólidos. O limite de detecção e quantificação obtidos foram de 0,035 e 0,117 μg, respectivamente. Por fim, foi desenvolvido um método analítico para a determinação de mercúrio em amostras de sangue (SERONORM® LEVEL III e II) e urina (SERONORM®, Clincheck Control nível I e II lote 432 e nível II lote 923) certificadas, de forma direta, utilizando nanopartículas de ouro. O método foi comparado ao método já existente que utiliza permanganato de potássio como agente oxidante. O limite de detecção e quantificação obtidos foram de 0,057 e 0,190 ng, respectivamente.Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPqporUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em QuímicaUFSMBrasilQuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessCaClCloroSrIIodoMercúrioAmostra sólidaAmostragem diretaHR-CS GF AASHR-CS GF MASChlorineIodineMercurySolid sampleDirect samplingCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICADeterminação de Cl, I e Hg de forma direta em amostras diversas por espectrometria de absorção atômica e molecular de alta resolução com fonte contínua em forno de grafiteDetermination of CI, I, and Hg directly in different samples by high-resolution continuum source atomic and molecular absorption spectrometry in graphite furnaceinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisNascimento, Paulo Cícero dohttp://lattes.cnpq.br/7151513617218161Nascimento, Denise Bohrer dohttp://lattes.cnpq.br/9817093263802769Silva, Carine Vianahttp://lattes.cnpq.br/2004872342535591Dessuy, Morgana Bazzanhttp://lattes.cnpq.br/2433844803067772Kunz, Simone Noremberghttp://lattes.cnpq.br/0979416016892842http://lattes.cnpq.br/9715932220582333Guarda, Ananda Fagundes100600000000600bedcb1a9-273c-4834-b87e-d52821567107b5251a77-f2e7-4cd5-82ed-4a27ef99a3936b8b95ca-db02-4fbf-80ea-848fdb5e586e361b08b4-ebc1-4f76-8bdf-d6c002274e18fb8059b9-2e5b-4de2-9367-862db74cd5a4582e69f8-1578-4c5b-b12a-91e530739af5reponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALTES_PPGQUIMICA_2017_GUARDA_ANANDA.pdfTES_PPGQUIMICA_2017_GUARDA_ANANDA.pdfTese de Doutoradoapplication/pdf3715681http://repositorio.ufsm.br/bitstream/1/13272/1/TES_PPGQUIMICA_2017_GUARDA_ANANDA.pdf4aafe68538f70a283bac7038ae7b4430MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

description |
Three analytical methods were developed for the determination of chlorine, iodine and mercury in solid and liquid samples, directly by high resolution continuum source atomic and molecular absorption spectrometry in graphite furnace. The first method objected the determination of chlorine in solid and slurry samples of different natures and chlorine contents (CRM 81002b human hair, SRM 1568b rice flour, ERM EC681 polyethylene, CRM BCR 460 coal, SRM 2692c bituminous coal, SRM 1575 sheet Of pine, CRM 686-1 iron oxide, SRM 1549 powdered milk) through the molecular formation of CaCl. The results were compared with those already available for the SrCl molecule and were superior, especially in samples with a high calcium content. The limit of detection and quantification obtained for the two molecular absorption lines of CaCl were 2.6 and 8.7 ng (620.862 nm) and 14.2 and 61.6 ng (377.501 nm), respectively. The iodine determination was performed through the formation of the SrI molecule in two samples of medicines containing iodine. The accuracy of the method was proved by comparative analysis by inductively coupled plasma mass spectrometry. The results obtained were higher compared to the existing BaI molecule that does not provide direct determination in solids. The limit of detection and quantification obtained were 0.035 and 0.117 μg, respectively. Finally, an analytical method for the determination of mercury in blood samples (SERONORM® LEVEL III and II) and urine (SERONORM®, Clincheck Control level I and II batch 432 and level II batch 923) were developed, directly, using gold nanoparticles. The method was compared to the existing method that uses potassium permanganate as oxidizing agent. The limit of detection and quantification obtained were 0.057 and 0.190 ng, respectively. |
