英文摘要: Abstract(#br)The dielectric barrier discharge (DBD) non-thermal plasma was used to modify the phosphoric acid activated carbon (AC) for enhancing its adsorption performance of Cu(II). The BET, SEM-EDX, FT-IR, elemental analysis and XPS techniques were employed to determine the textural structure and surface chemistry of the raw and plasma modified ACs. The results indicate that the ACs after using plasma modification have much higher Cu(II) adsorption capacity, irrespective of different adsorption conditions, such as solution pH, temperature, dosage and agitation speed. Importantly, the adsorption capacity of Cu(II) on AC has a non-monotonic variation (increasing at first and then decreasing) with the plasma modification time. The optimum modification time was 7.5 min in this study and...
