A New Methodological Approach to Study the Interaction of Humic Acids, Minerals and Polyvalent Cations in Soil
(Taylor & Francis, 2024-02-20)A new methodological approach of humic acid (HA) extraction is applied to study soil samples with contrasting management regimes: natural vegetation (NV) and agricultural (A). This innovative approach involves a modification ... -
Aggregation kinetics of humic acids in the presence of calcium ions
(2013)The aggregation kinetics of a humic acid (HA) sample as a function of Ca2+ concentration at pH 5, 7 and 9 was investigated. UV–VIS spectroscopy was employed to quantify the progress of the aggregation reaction, and ...
