Spectroscopic characterization of humic substances isolated from sediment of an area of sugarcane cultivation
(2013-08-01)
Humic substances (HS) have an important environmental property, interacting with metal species and influencing their transport, accumulation, and bioavailability. In this study, the HS of sediment from an area of intensive ...
Peat humic substances enriched with nutrients for agricultural applications: Competition between nutrients and non-essential metals present in tropical soils
(2010-05-01)
Improved agricultural productivity, and reduction of environmental impacts, require studies of the interactions between different soil components. Fertilizers marketed as organic or natural , such as peats or humic ...
Influence of the Extractant on the Complexing Capacity of Humic Substances from Peat for Macro and Micronutrients Using Continuous Flow: Agricultural Application and Environmental Impacts
(Soc Brasileira Quimica, 2013-12-01)
The aim of the present work was to optimize a procedure for extraction of humic substances (HS) from peat, using continuous flow with different extractants (NaOH, KOH and Na4P2O7). The influence of extractant on the ...
Caracterização estrutural das substâncias húmicas aquáticas extraídas dos rios itapanhaú e ribeira de iguape
(Sociedade Brasileira de Química, 2011-01-01)
The knowledge of the structure characteristic of the Organic Matter is important for the understanding of the natural process. In this context aquatic humic substances (principal fraction) were isolated from water sample ...

Sensing atrazine herbicide degradation products through their interactions with humic substances by surface-enhanced raman scattering
(2021-06-01)
In this work, we have developed a simple method to carry out the quantitative analysis of deethylhydroxyatrazine (DEHA), the most abundant metabolite of atrazine herbicide (ATZ), based on the surface-enhanced Raman scattering ...
