논문 초록 (Abstract)
Biochar was produced from Korean cabbage (KC), rice straw (RS) and wood chip (WC) and the use as alternative adsorbents to activated carbon (AC) in wastewater treatment was investigated. Congo red (CR) and crystal violet (CV) were used as a model anionic and cationic dye , respectively. Initial solution pH had little effect on CR and CV adsorption onto all biochars except for AC on CR. The isotherm m odels and kinetic data showed that adsorption of CR and CV onto all bi ochars were dominantly by chemisorption. All biochars had lower adsorpt ion capacity for CR than AC. KC showed higher Langmuir maximum adsor ption capacity (1304 mg/g) than AC (271.0 mg/g), RS (620.3 mg/g) and W C (195.6 mg/g) for CV. KC may be a good alternative to conventiona l AC as cheap, superb and industrially viable adsorbent for removal of c ationic dyes in wastewater. (C) 2016 Elsevier Ltd. All rights reserved.
