Pb(II) Selectivity of Oxygen-Functionalized Lignite-Based Carbon Material in the Presence of Competitive Cu(II)/Cd(II) Interference

Abstract A series of lignite-derived activated carbons (CK-400-CK-700) was prepared by KOH activation to clarify the effects of pore structure and surface oxygen functionality on Pb(II) adsorption. Although the BET surface area increased from 456.60 to 1300.70 m2·g–1 with activat...

Analysis of the Composition and Thermogravimetric Kinetics of Vacuum Residue from Karamay

Vacuum residue (VR) is one of the more difficult heavy fractions to process in petroleum refining, and the development of clean utilization technologies for vacuum residue has become a major research focus in the petrochemical industry. This paper discusses the compositional and...
