Resumo: This paper evaluated the effect of the combination of two non-industrial methods to treat fence posts of Eucalyptus grandis, on the penetration and retention of water borne preservative. Thus, four fences with 2.20 m in length were treated by replacement of sap and simple diffusion alone and other four ones have combined the two techniques, with water-borne CCB 50% preservative at a concentration of 3.5%. After each treatment condition, the pieces were seasoned in the shade for 30 days. Disks were taken at 0.60 and 1.60 m from the base of the pieces which had one side sanded for analysis of the penetration of the preservative using a solution of chrome azurol S. From the same parts, test specimens were also manufactured in diametrically opposed positions with dimensions of approximately 3.0 x 2.0 x 2.5 cm (radial x tangential x longitudinal) to analyze the retention of the element copper by atomic absorption spectrophotometry method and boron by visible spectrophotometry with azomethine-H, also known as colorimetry. The retention values obtained were compared with the minimum recommended by the Brazilian Association of Technical Standards – ABNT for water borne preservatives which is 6.5 kg of active ingredients per m³ of wood. The penetration achieved by the combined method was considered sufficient for non-industrial treatment, while the retention values were higher than the retention of at least 6.5 kg of active ingredients / m³ of treated wood in all positions and portions evaluated.

Para tanto, quatro moirões com 2,20 m de comprimento foram submetidos ao tratamento de substituição de seiva e difusão simples isoladamente e outros quatro à combinação das duas técnicas, com preservativo hidrossolúvel à base de CCB com 50% de ingredientes ativos, numa concentração de 3,5% de sal seco. Após cada condição de tratamento, os moirões foram secos à sombra durante 30 dias. Foram retirados discos a 0,60 e 1,60 m da base das peças os quais tiveram uma das faces lixadas para análise da penetração do preservativo hidrossolúvel utilizando uma solução de cromoazurol S. Destas mesmas peças, também se confeccionaram, em posições diametralmente opostas, corpos de prova adjacentes com dimensões de aproximadamente 3,0 x 2,0 x 2,5 cm (tangencial x radial x longitudinal) em duas regiões na direção periferia-centro dos discos, para a análise da retenção do elemento cobre pelo método de espectrofotometria de absorção atômica e do boro por espectrofotometria visível com azometina-H, também conhecido por colorimetria. Os valores de retenção obtidos foram comparados com a mínima recomendada pela Associação Brasileira de Normas Técnicas para preservativos hidrossolúveis que é de 6,5 kg i.a/m³ de madeira. A penetração obtida pelo método combinado foi considerada suficiente para tratamentos não industriais, enquanto os valores de retenção foram superiores a retenção mínima de 6,5 kg de ingredientes ativos/m³ de madeira tratada na maioria das posições e porções avaliadas.Universidade Federal de Santa Maria2011-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/381610.5902/198050983816Ciência Florestal; Vol. 21 No. 3 (2011); 579-589Ciência Florestal; v. 21 n. 3 (2011); 579-5891980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3816/2253Modes, Karina SoaresBeltrame, RafaelVivian, Magnos AlanSantini, Elio JoséHaselein, Clovis RobertoSouza, Joel Telles deinfo:eu-repo/semantics/openAccess2017-05-03T18:00:52Zoai:ojs.pkp.sfu.ca:article/3816Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-03T18:00:52Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
