In this article, a new surface imprinted polymer D301-g-IIPDMC is successfully prepared using AuCl4− as a template. The adsorption and recognition performances of D301-g-IIPDMC for AuCl4− are studied by using a static method and competitive adsorption experiment. The experimental results show that D301-g-IIPDMC possesses very strong adsorption affinity and excellent recognition for AuCl4−. The adsorption capacity of D301-g-IIPDMC for AuCl4− is 831.08 mg/g, and the selectivity coefficient relative to CuCl42− is 128. The adsorption behavior is an endothermic spontaneous process, and fit well with pseudo-second order kinetic model and Freundlich adsorption isotherm model. Besides, D301-g-IIPDMC is desorbed easily and exhibits excellent reusability.

An, Fu-Qiang,Wu, Rui-Yan,Li, Min,Yuan, Zhi-Guo,Hu, Tuo-Ping,Gao, Jian-Feng Korean Chemical Society 2017 대한화학회지 Vol.61 No.5
Efficiently removing Al(III) from rare earth is very significant because even trace amount of Al(III) can cause serious harm to the rare earth materials. In this paper, a nitrogen-containing activated carbon, AC-P700, was synthesized using peas as raw materials. The AC-P700 was characterized by surface area analyzer, FT-IR, and XPS methods. The adsorption and recognition properties of AC-P700 towards Al(III) were investigated, and the recognition mechanism was also analyzed. The BET special surface area of AC-P700 was $1277.1m^2{\cdot}g^{-1}$, and the average pore diameter was 1.90 nm. The AC-P700 possesses strong adsorption affinity and excellent recognition selectivity towards Al(III). The adsorption capacity for Al(III) could reach to $0.53mmol{\cdot}g^{-1}$, and relative selectivity coefficients relative to La(III) and Ce(III) is 9.6 and 8.7, respectively. Besides, AC-P700 possesses better regeneration ability and reusability.

Rare earth elements are an important strategic resource. However, a trace of Fe(III) impurity has serious adverse impact on the performance of rare earth materials. We synthesized a novel nitrogen-containing carbon material, ACLR-400, using lotus root as raw materials. The ACLR-400 was characterized by surface area analyzer, elemental analysis and FT-IR. The selectivity and removal efficiency of ACLR-400 towards Fe(III) were also investigated. The BET specific surface area of ACLR-400 was 68.44m2·g−1, and the average pore diameter was 12.54 nm. With abundant nitrogen- containing functional groups and well-developed internal pore structure, ACLR-400 possesses strong adsorption affinity, excellent selectivity and removal efficiency for Fe(III). The adsorption capacity of ACLR-400 towards Fe(III) could reach to 0.46mmol·g−1, selectivity coefficient with respect to La(III) was 8.9, and removal efficiency was 99.61%. The adsorption isotherm data greatly obey the Freundlich isotherm. In addition, ACLR-400 can be regenerated easily and possesses better regeneration ability and reusability.

Effective removal of anilines using porous activated carbon based on ureaformaldehyde resin
Fu-Qiang An,Dong Zhang,Xiao-Xia Yue,Guo-Li Ou,Jian-Feng Gao,Tuo-Ping Hu 한국화학공학회 2016 Korean Journal of Chemical Engineering Vol.33 No.2
The effective removal of aniline and its derivatives from wastewater is very important due to the high toxicity. Adsorption with a high-performance adsorbent is an efficient pathway. A novel activated carbon, ACUF-700, was synthesized using homemade ureaformaldehyde resin as the major carbon source carbonized at 700 oC. ACUF-700 is characterized by surface area analyzer, FTIR, elemental analyzer, and SEM. The adsorption properties of ACUF-700 towards anilines are also investigated by using batch methods. The test results showed that the ACUF-700 possesses higher specific surface area and narrower pore size distribution. In virtue of its developed pore structure and nitrogencontaining chemical groups, the adsorption capacities towards aniline, p-toluidine and p-chloroaniline could reach 95.6, 108.1 and 128.9mg/g, respectively. The adsorption process could be well described by the intra-particle mass transfer diffusion model and Sips model. Besides, ACUF700 was regenerated easily using diluted hydrochloric acid solution as eluent and ACUF700 possesses better reusability.

Nitrogen-containing porous carbons, the 800SP-NH3, were synthesized using sunflower plates as the major carbon source carbonized at 800 oC and activated with concentrated aqueous ammonia at the same temperature. The porous carbons were characterized by nitrogen physical adsorption-desorption, surface area analyzer, FT-IR, and SEM. The adsorption properties of the porous carbons towards phenols were also investigated by batch methods. The test results show that the average pore diameter of porous carbon is smaller than 2 nm, and nitrogen-containing chemical groups are formed on its surface. The adsorption capacity for phenol, 4-chlorophenol, and p-nitrophenol is 316.5mg/g, 330.24mg/g and 387.62mg/g due to its developed pore structure and nitrogen-containing chemical groups. The adsorption isotherm data greatly obey the Langmuir model.
