Enhanced adsorption capacity of antibiotics by calamus-biochar with phosphoric acid modification: Performance assessment and mechanism analysis
Background
Adsorption is one of the effective methods to remove antibiotics from water. Plant-based biochar can be effectively modified to enhance the adsorption capabilities of antibiotics.
Methods
Calamus biochar (PBC) was modified by phosphoric acid to study its adsorption efficacy on erythromycin (ERY) and sulfamethoxazole (SMX).
Significant Findings
PBC had a pore density of 0.771 m3·g−1, an average pore size of 5.14 nm, and an enormous surface area of 797 m2·g−1. PBC had been shown to incorporate a substantial quantity of functional groups containing oxygen by FTIR and XPS investigations. With these surface chemical and physical characteristics, PBC adsorbed 325 mg·g−1 of ERY and 216 mg·g−1 of SMX, which was tenfold higher compared to that of unmodified biochar and industrial-activated carbons. Quantitative analysis of adsorption mechanisms showed that the adsorption of ERY by PBC mainly included oxygen-containing functional group complexation and pore filling, whereas, the π-π interaction and pore filling were the leading mechanisms in the adsorption process of SMX. This research offers insights into the preparation of plant biochar with excellent antibiotic adsorption performance.
期刊介绍：
Journal of the Taiwan Institute of Chemical Engineers (formerly known as Journal of the Chinese Institute of Chemical Engineers) publishes original works, from fundamental principles to practical applications, in the broad field of chemical engineering with special focus on three aspects: Chemical and Biomolecular Science and Technology, Energy and Environmental Science and Technology, and Materials Science and Technology. Authors should choose for their manuscript an appropriate aspect section and a few related classifications when submitting to the journal online.
