In order to improve the Cd2+ adsorption ability, the granular activated carbon (GAC) was modified with different treatments, and the Cd2+ removal efficiencies (REs) by the treated GACs were then comparatively investigated under different conditions. The surface physical-chemical properties of these carbons were further characterized in virtue of BET and Boehm’s titration, etc. The results demonstrate that the specific surface area and surface oxy acidity functional groups of GAC changed to some certain after the different treatments, especially for that with HNO3 oxidizing. It therefore led to an improvement of Cd2+ adsorption ability, and the corresponding REs by the N-GACs that were respectively modified with 10% and 70% HNO3 were significantly higher than that by the original GAC (i.e., 41% and 57% vs. 10%). pH was found to be the most vital influencing factor for the Cd2+ adsorption, and the Cd2+ REs by the tested GACs were all increased with an elevation in the pH value.

In the present research, activated carbon-supported sulfonic acid catalysts were synthesized and tested as pretreatment agents for the conversion of switchgrass into glucose. The catalysts were synthesized by reacting sulfuric acid, methanesulfonic acid, and p-toluenesulfonic acid with activated carbon. The characterization of catalysts suggested an increase in surface acidities, while surface area and pore volumes decreased because of sulfonation. Batch experiments were performed in 125 mL serum bottles to investigate the effects of temperature (30, 60, and 90 °C), reaction time (90 and 120 min) on the yields of glucose. Enzymatic hydrolysis of pretreated switchgrass using Ctec2 yielded up to 57.13% glucose. Durability tests indicated that sulfonic solid-impregnated carbon catalysts were able to maintain activity even after three cycles. From the results obtained, the solid acid catalysts appear to serve as effective pretreatment agents and can potentially reduce the use of conventional liquid acids and bases in biomass-into-biofuel production.
