Caffeine removal by Gliricidia sepium biochar: Influence of pyrolysis temperature and physicochemical properties
Popis výsledku v původním jazyce
The present study aimed to envisage the effect of physicochemical properties on the performance of Gliricidia sepium biochar (GBC) pyrolyzed at 300, 500, and 700 Celsius in the removal caffeine (CFN) a pharmaceutical and personal care product, from water. The physicochemical properties of GBC were characterized by proximate and ultimate analysis, BET, SEM, FTIR, and Raman spectroscopy. The adsorption batch experiment was carried out at various pH values (pH 3 to 10), mixing times (up to 24 h), and initial CFN concentration (10 to 500 mg/L). The FTIR analysis revealed the loss of polar functional groups on the surface of GBC derived at high temperatures. The redshifted and blue-shifted Raman peaks indicate the condensation of small molecules on GBC. The GBC derived at 700 Celsius demonstrated high CFN adsorption capacity (16,26 mg/g) due to its high surface area and aromaticity. The highest adsorption of CFN was occurred at acidic pH range from 3,5 to 4,5 due to the existence of nonspecific at
