Abstract

ABSTRACT: Wastewater contains dye or pharmaceuticals could imply severe environmental impacts due to their toxicity to ecosystems and, consequently, the generation of human health risks. In this work, the orange peel biochar was prepared through pyrolysis, and then Mg/Al-layered double hydroxide (Mg/Al-LDHs) was grown on the surface of the biochar (BC@Mg/Al-LDHs) by hydrothermal method. The material was characterised by SEM, TEM, XRD, XPS and other techniques. The adsorption performance, adsorption isotherms, kinetics and thermodynamics of BC@Mg/Al-LDHs on methylene blue (MB) or tetracycline hydrochloride (TC) were investigated. The results showed that the maximum adsorption capacity of BC@Mg/Al-LDHs for MB and TC were 75.98 and 29.08 mg/g, respectively. The adsorption equilibrium was reached within 30 minutes, and removal percent was 93.99 and 62.06% for MB and TC, respectively. The obtained results investigate that the prepared BC@Mg/Al-LDHs materials for a broad range of applications in dye and pharmaceuticals separation from the water environment.
