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 ...
Aquatic Humic Substances: Relationship Between Origin and Complexing Capacity
(Springer, 2018-05-01)
Aiming to determine the relationship between source and complexing capacity, humic substances obtained from three sites (Sorocaba and Itapanhau Brasilian rivers, and Xochimilco Lake in Mexico) were studied. Copper, manganese, ...
Complexing capacity of natural waters carrying a great amount of suspended matter
(Pergamon-Elsevier Science Ltd, 2007-11)
The cadmium binding properties of waters of the superior section of the Rio de la Plata estuarine were determined over a three-year period. Samples were collected at different hydrodynamic conditions. The complexing capacity ...
