Preconcentration of polar phenolic compounds from water samples and soil extract by liquid-phase microextraction and determination via liquid chromatography with ultraviolet detection. Author(s): DOLATTO, R. G.; MESSERSCHMIDT, I.; PEREIRA, B. F.; MARTINAZZO, R.; ABATE, G. Repository: BDPA Publication year: 2016
Carbon distribution in humic substance fractions extracted from soils treated with charcoal (biochar). Author(s): MADARI, B. E.; LIMA, L. B.; SILVA, M. A. S.; NOVOTNY, E. H.; ALCANTARA, F. A. de; CARVALHO, M. T. M.; PETTER, F. A. Biochar incorporation into the soil is a proposed C sequestration strategy. How newly applied biochar affects C accumulation in the soil is therefore a relevant question. This study presents part of t... ... Repository: BDPA Publication year: 2013
