Estudio de las propiedades adsortivas de residuos lignocelulósicos para la eliminación de irgasán, ibuprofeno, amoxicilina y paracetamol presente en residuos líquidos

Abstract

The present work studies the adsorptive properties of lignocellulosic residues for the removal of irgasan, ibuprofen, amoxicillin and paracetamol present in wastewater, by evaluating the state of the art and statistics of scientific information. The evaluation of the state of the art defined the scope of the study, the statistical analysis of variance allowed to establish hierarchies in the use of lignocellulosic materials as adsorbent and the correlation analysis was carried out to define the influencing conditions in the removal of contaminants. Research on the subject increased from 2.5 to 21.2%, of the total of publications analyzed (n = 80) in the last decade, the removal of amoxicillin was the most studied (33.8%), followed by ibuprofen (23.8%), paracetamol (23.8%) and irgasan (15%). From the analysis of variance for the four CEs, it was obtained that the highest adsorption capacity according to the type of biomass was presented by herbaceous and agricultural biomass, with 90 mg / g for irgasan, 48.2 mg / g for ibuprofen, 152.5 mg / g for amoxicillin and 74 mg / g for paracetamol. The correlation analysis determined that the influencing conditions in the removal of CEs are the surface area and pH since they presented a linear relationship with the highest adsorption capacity.
