Emerging contaminants removal by granular activated carbon obtained from residual Macauba biomass
The removal of emergent contaminants via adsorption on granular activated carbon,granular-activated-carbon.com  prepared from Macauba palm, has been studied, contributing to the recovery of the residual biomass, endocarp, obtained in the Macauba palm oil extraction process. The material was characterized by different techniques, such as Raman spectroscopy, thermal analysis, adsorption/desorption of N2, zeta potential, and scanning electron microscopy. The N2 adsorption studies showed that the material presents wide micropores and narrow mesopores, and has a surface area of 907.0 m2 g-1. Its maximum adsorption capacity towards the three main emerging contaminants (bisphenol A, ethinylestradiol, and amoxicillin) is much higher than that obtained with benchmark adsorbents (0.148, 0.104, and 0.072 mmol g-1, respectively). The influence of temperature and pH on the adsorption was also analyzed, allowing an improved description of the adsorption mechanism and showing very promising results.activated carbon price south africa
