Resumo: Aiming to develop analytical methodology for the determination of available molybdenum in soil and organic fertilizer, it was improved a procedure using a 1.0 mol. L-1 ammonium acetate extraction solution, pH 6.5-7.0, shaking for 7 hours, and signal measurement by Graphite Furnace Atomic Absorption Spectrometry (GFAAS, 2650 °C atomization temperature; detection limit of 2.0 ng Mo.mL-1).

Com o objetivo de desenvolver metodologia analítica para a determinação de molibdênio (fração disponível), em amostras de solo e de fertilizante orgânico, aperfeiçoou-se procedimento que utiliza solução de acetato de amônio 1,0 mol.L-1 como meio extrator, pH 6,5 a 7,0, agitação por 7 horas e medida por Espectrometria de Absorção Atômica em Forno de Grafite (GFAAS, temperatura de atomização de 2650 °C, limite de detecção de 2,0 ng Mo. mL-1).Universidade Federal de Santa Maria1996-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32110.5902/19805098321Ciência Florestal; Vol. 6 No. 1 (1996); 15-20Ciência Florestal; v. 6 n. 1 (1996); 15-201980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/321/189Canto, Maria Leopoldina Keller doMartins, Ayrton Figueiredoinfo:eu-repo/semantics/openAccess2017-06-14T12:12:58Zoai:ojs.pkp.sfu.ca:article/321Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-14T12:12:58Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
