| Sumario: | Humic acids (HAs) are the main and most abundant components of organic matter (OM), they were evaluated by spectroscopic parameters, after a process of agglomeration, coagulation and microfiltration in the presence of iron (Fe3+) as a coagulant agent and by means of quantification with the calibration method. Additionally, the behavior of humic macromolecule in presence of metal was analyzed physicochemically and adjusting the pH to 5 to favour the deprotonation of the carboxylic groups (- COOH), stabilizing the negative charges with a minimum but effective Fe3+salt (3 mM) concentration. Managing to eliminate an average of 96% the HA as OM in solution. The kinetics of HA-Fe interaction process were very short, less than 5 min. The spectra show a great similarity in relation to the absorbances, however, it is recommended to carry out the microfiltration in the first 30 min of reaction. |
