From rice-husk waste to selective BTEX adsorbents: modified MWCNTs reveal a co-adsorption swing effect and improve field monitoring

Key Points

• To investigate the capacity of modified MWCNTs from rice husk for selective adsorption of gaseous BTEX and the effects of co-adsorption.
• Utilized modified multi-walled carbon nanotubes (MWCNTs) derived from rice husk.
• Conducted adsorption tests for gaseous BTEX compounds, focusing on xylene.
• Performed field tests using NIOSH 1501 protocol for comparing effectiveness against commercial adsorbents.
• Modified MWCNTs showed enhanced adsorption of BTEX gases, particularly xylene.
• Field tests indicated superior performance of MWCNTs over commercial activated carbon.
