Activated carbons from avocado seed: optimisation and application for removal of several emerging organic compounds.

摘要: In this study, avocado seed was successfully used as raw material for producing activated carbons by conventional pyrolysis. order to determine the best condition produce carbons, a 22 full-factorial design of experiment (DOE) with three central points employed varying temperature and time The two evaluated factors (temperature pyrolysis) strongly influenced SBET, pore volumes, hydrophobicity–hydrophilicity ratio (HI) functional groups values; both had negative effect over volumes which means that increasing values leads decrease these responses; on other hand, regards HI, caused positive their values, HI has an enhancement its values. produced carbon exhibited high specific surface areas in range 1122–1584 m2 g−1. Surface characterisation revealed (ASACs) have hydrophilic surfaces predominantly acidic surfaces. prepared ASACs were adsorption 25 emerging organic compounds such 10 pharmaceuticals 15 phenolic presented uptake all pollutants.
