Interaction Study Between Humin and Phosphate: Possible Environmental Remediation for Domestic Wastewater
(2017-01-01)
The increase in demand for food due to the rapid population growth in recent years has raised the use of fertilizers, particularly phosphate salts. This fact has contributed to the excess amount of phosphorus species in ...
Adsorption and release of micronutrients by humin extracted from peat samples
(2013-06-20)
The objective of this work was to investigate the adsorption of micronutrients in humin and to verify the ability to release these elements in water. The first step was to determine the adsorption capacity of humin for ...
Interactions between humin and potentially toxic metals: Prospects for its utilization as an environmental repair agent
(2015-06-01)
The disposal of potentially toxic metals in aquatic systems is an issue that mainly involves densely populated regions that dump these contaminants into the environment, either directly or indirectly. Substances that are ...
Spectroscopic characterization of the reduction and removal of chromium (VI) by tropical peat and humin
(Elsevier B.V., 2012-01-01)
The reduction of Cr(VI) to Cr(III) in aqueous solution, and the subsequent removal of Cr(III) using in natura peat or its humin fraction, was characterized by electron paramagnetic resonance (EPR), ultraviolet-visible ...
Influence of alkaline extraction on the characteristics of humic substances in Brazilian soils
(Elsevier B.V., 2005-08-01)
An investigation was made of the influence of alkaline extraction on the characteristics of humic substances extracted from Brazilian soil samples. Humic substances (HS) from seven different soils samples collected in ...
Sequential exhaustive extraction of a Mollisol soil, and characterizations of humic components, including humin, by solid and solution state NMR.
(European Journal of Soil Science, Oxford, v. 59, n. 3, p. 505-516, Jun. 2008., 2016)
Soil organic matter as a function of nitrogen fertilization in crop successions
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2005-08-01)
A interdependência dos ciclos de C e N reflete-se nos teores de matéria orgânica do solo (MOS). em um delineamento experimental em blocos casualizados, com parcelas sub-subdivididas, tendo como tratamento principal cinco ...
Absorcao de nitrogenio do solo pelo milho influenciada pela adicao de diferentes residuos de culturas.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, n.4, p.481-486, abr. 1998., 1998)
Turfeiras da Serra do Espinhaço Meridional - MG: II - influência da drenagem na composição elementar e substâncias húmicas
(Sociedade Brasileira de Ciência do Solo, 2009)
As turfeiras são Organossolos que resultam de condições ecológicas ideais ao acúmulo de material orgânico, controladas pelos sistemas geomorfológicos e processos geológicos e climáticos globais. Sua constituição física, ...
Organic matter fractions and soil fertility under the influence of liming, vermicompost and cattle manure
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2003-01-01)
Os efeitos do vermicomposto de esterco de curral associado à calagem em atributos da fertilidade do solo foram avaliados através de experimento em vasos empregando um Latossolo Vermelho, distrófico, textura média. Cinco ...
