Oil palm empty fruit bunch-based nanocellulose as a super-adsorbent for water remediation.

Oil palm empty fruit bunch (EFB)-based nanocellulose (NC) was successfully produced as a super-adsorbent for water remediation via sulfuric (NCS) and phosphoric (NCP) acid hydrolysis and functionalized with activated carbon (AC). The formation of sulfonic groups on the NCS surface could achieve higher remediation capabilities than that of EFB-NCP. In a very short period, 2 wt.
