Fibra de coco no tratamento de efluentes contaminados com Cr(VI). Repository: BDPA Publication year: 2006
Efeito da toxicidade de Cr (VI) e Zn (II) no crescimento do fungo filamentoso Aspergillus niger isolado de efluente industrial. Processos convencionais de tratamento de efluentes utilizam microrganismos vivos, o que sugere limitações relativas à toxicidade de metais para os microrganismos. O experimento consistiu em adicionar... ... Repository: BDPA Publication year: 2011
Especiação de Cr(VI) em fertilizantes orgânicos por meio da extração em ponto nuvem e otimização através do planejamento experimental Doehlert. Visando atender às exigências da Instrução Normativa (IN) n.7 do Ministério da Agricultura, Pecuária e Abastecimento (MAPA)[1] que determina limites máximos de Cr(VI) em fertilizantes orgânicos menore... ...

Quantificação e solubilidade de Cr-VI em talude de pilha de estéril sob experimento de revegetação e potencial toxicidade aquática em caso de escoamento superficial. Repository: BDPA Publication year: 2019
Chromium speciation in organic fertilizer by cloud point extraction and optimization through experimental Doehlert design as support for legislative aspects. Brazilian and EU legislation establishes 2 mg kg?1 as the maximum limit of Cr(VI) in organic fertilizers. A procedure involving chromium speciation was developed. With this approach, the interference... ... Repository: BDPA Publication year: 2021
Evaluatin of metabisulfite and a commercial stee wool for removing chromium (VI) from wastewater. Efficiency of metabisulfite and a commercial steel wool as reducing agents in the removal of Cr(VI) from wastewaters was evaluated. Chromium( VI) was converted to Cr(III), precipitated with NaOH, and... ... Repository: BDPA Publication year: 2010
VIS-NIRS to predict meat quality is anatomical point specific. The Vis-NIRS is a non-destructive, simple, rapid, and safe method for evaluating meat quality. Studies using VIS/NIRS to predict the meat quality are based mainly in information collected on longissim... ... Repository: BDPA Publication year: 2018
Cr/Al oxide as solid acid catalyst to afford babassu biodisel. In this work, it was described the preparation and the characterization of a solid acid catalyst obtained by the mixture of Cr/Al oxides (CRAL). The catalyst was tested in the transesterification reac... ... Repository: BDPA Publication year: 2015
