The Role of Concentration and Solvent Character in the Molecular Organization of Humic Acids
Molecules, 2016 The molecular organization of humic acids in different aqueous solutions was studied over a wide concentration range (0.01–10 g·dm−3). Solutions of humic acids were prepared in three different media: NaOH, NaCl, and NaOH neutralized by HCl after ...

Biologia Plantarum, 1959 1. Leaves of sugar-beet (Beta saccharifera), which had assimilated active carbon dioxide C14O2, were subjected to the process of humification in soil. After three to five months of humification the dried soil was extracted with ether-alcohol, then with sodium or potassium hydroxide; the humic acids were separated from fulvic acids with hydrochloric ...

Initial performance of corn in response to treatment of seeds with humic acids isolated from bokashi
Revista Ceres, 2016 The humified organic matter presents bioactivity similar to the auxinic effect. As bokashi is produced by a special process of humification, information is needed about the bioactive potential of its humic acids.

TLC Determination of Aquatic Humic Acids
Water Science and Technology, 1992 Humic acids are mostly determined by spectroscopic methods, although they are not accurate enough, because humic acids possess no maximum absorption at any wavelength in the ultraviolet and visible spectrum. In this contribution the accurate and precise method for aquatic humic acids determination, using thin layer chromatography, was worked out ...
