Substâncias húmicas de turfa: estudo dos parâmetros que influenciam no processo de extração alcalina
(Sociedade Brasileira de Química, 2000-08-01)
This study reports the parameters which influence on extraction of humic substances (HS) from peat. The yield, organic and inorganic contend, E4/E6 ratio and elemental composition (C,H,N) of the extracted HS have been ...
Humic Acids: Structural Properties And Multiple Functionalities For Novel Technological Developments
(Elsevier Science BVAmsterdam, 2016)
Realistic soil C sink estimate in dry forests of western Argentina based on humic substance content
(Elsevier, 2013-02)
Due to high temporal variation of soil organic matter in arid regions, estimates of annual sequestered C might be overestimate. We assessed the soil stable organic matter (humic substances) in the transitional area between ...
Spectroscopic and elementary characterization of humic substances in organic substrates
(2018-01-01)
The humic substances, major constituents of the organic matter of the substrates, play an important role in plant development, including: the availability of nutrients, the generation of negative charges (CEC) and the ...
EFFECTS OF HUMIC AND OXALIC ACID IN WOOD BIODEGRADATION BY Gloeophyllum trabeum
(Sociedad Chilena de Química, 2010)
Atrazine interaction with tropical humic substances by Enzyme Linked Immunosorbent Assay
(E D P Sciences, 1998-04-01)
Enzyme-Linked Immunosorbent Assay (ELISA) has been evaluated by analyzing rich-humic water samples from tropical rivers. The samples were spiked with atrazine at ppb level Different pHs (4 to 9) and humic concentrations ...
A structural conformation study of aquatic humic acid
(2006-10-16)
In the present work, aquatic humic substances (HS) were extracted by use of adsorbent XAD 8 and the acid humic fraction (AH) was separated throught acidification. After being purified by Hyphan resin and dialyze, the aquatic ...
Chemical nature of soil humified fractions and their bioactivity.
