    Synthesis of Potassium Tetratitanate—Based Molecularly Imprinted Polymer for Selective Adsorption of Dibenzothiophene by Wanzhen Xu, Xudong Zheng, Mengying Gan, Wenjing Zhu, Yunlei Zhang, Yongsheng Yan

    Published 2013-12-01
    “…Thermodynamic parameters demonstrated that the adsorption process was spontaneous and endothermic. Thus, based on the study results it can be concluded that the synthesized adsorbent (i.e. …”

    A New Sr(II) Ion-Imprinted Polymer Grafted onto Potassium Titanate Whiskers: Synthesis and Adsorption Performance for the Selective Separation of Strontium Ions by Yan Liu, Jie Gao, Zulei Zhang, Jiangdong Dai, Jimin Xie, Yongsheng Yan

    Published 2010-01-01
    “…The values of the Gibbs' free energy (ΔG 0 ), standard entropy (ΔS 0 ) and standard enthalpy (ΔH 0 ) calculated from the adsorption data suggested that the adsorption of Sr(II) onto Sr(II)-IP was a spontaneous and endothermic process. The relative selectivity coefficients of Sr(II)-IP for Sr(II)/Cs(I) at different initial concentrations were 95.8, 320 and 1428.6, respectively, which were far greater than that of the non-imprinted polymer (NIP).…”

    Molecularly-Imprinted Material for Dibenzothiophene Recognition Prepared by Surface Imprinting Methods by Pingping Xu, Wanzhen Xu, Xiaojie Zhang, Jianming Pan, Yongsheng Yan

    Published 2009-12-01
    “…Values of the Gibbs' free energy (ΔG 0 ) ranged from −7.11 kJ/mol to −9.36 kJ/mol over the temperature interval 298–318 K, indicating that the adsorption was endothermic in nature. In addition, D-MIP exhibited selective recognition of DBT relative to other similar compounds such as benzothiophene (BT), 4-methyldibenzothiphene (4-MDBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT). …”

    Biosorption of Silver Ions by Biomass: Equilibrium, Kinetics and Thermodynamics by Hongxiang Ou, Yujun Song, Weihong Huang, Jianming Pan, Yonglai Xue, Chengwu Yi, Yongsheng Yan

    Published 2011-09-01
    “…The results indicated that the biosorption of Ag(I) ions onto P. lilacinus biomass was spontaneous and endothermic in nature. The FT-IR analysis results indicated that amine, carboxylic and hydroxyl groups were involved in the biosorption process.…”

    Performance of Poly(Styrene—Divinylbenzene) Magnetic Porous Microspheres Prepared by Suspension Polymerization for the Adsorption of 2, 4-Dichlorophenol and 2, 6-Dichlorophenol fro... by Ping Yu, Qilong Sun, Jianming Pan, Zhenjiang Tan, Jiangdong Dai, Yongsheng Yan, Feng Cheng

    Published 2013-07-01
    “…Thermodynamic parameters were calculated by the Gibbs free energy function, confirming that adsorption process was spontaneous and endothermic. In addition, the reusability performance of the Fe 3 O 4 @(St–DVB) magnetic porous microspheres was demonstrated by four repeated cycles.…”

    Adsorptive Removal of 2,6-Dichlorophenol from Aqueous Solution by Surfactant-Modified Palygorskite Sorbents: Equilibrium, Kinetics and Thermodynamics by Xue Wang, Jianming Pan, Wei Guan, Xiaohua Zou, Wei Hu, Yongsheng Yan, Chunxiang Li

    Published 2011-02-01
    “…Thermodynamic studies showed that the adsorption of 2,6-DCP onto the three sorbents examined occurred spontaneously and that the process was endothermic in nature. The results indicate that the surfactant-modified palygorskite exhibited a significant potential as a sorbent material for the removal of phenolic compounds from aqueous solution.…”
