| 1 | Adsorption behavior and mechanism of D113 resin for lanthanum显示文摘The sorption properties of macroporous weak acid resin (D113) for La3+ ion were studied by chemical analysis and IR spectra. Experimental results indicate that the D113 resin has a good adsorption ability for La3+ at pH = 6.0 in the HAc-NaAc medium. The statically saturated adsorption capacity is 273.3 mg/g. Separation coefficients of βLa3+/ Ce3+, βLa3+/ Gd3+, βLa3+/ Er3+, and βLa3+/ Y3+ are 2.29, 3.64, 4.27, and 0.627, respectively. The apparent activation energy of adsorption, Ea is 18.4 kJ/mol, the thermodynamics parameters H, S, and G of sorption are 4.53 kJ/mol, 61.8 J/(molK),-13.9 kJ/mol, respectively. The adsorption behavior of D113 for La3+ obeys the Freundlich isotherm. La3+adsorbed on resin can be eluted by 2.0 mol/L HCl quantitatively. | SHU Zengnian XIONG Chunhua SHEN Qiuxian YAO Caiping GU Zhenyu | 2007 | Rare Metals2007，26，6： | 7 |
| 2 | Adsorption behavior of Pd(Ⅱ) from aqueous solutions by D201 resin显示文摘The adsorption and desorption behaviors of Pd(Ⅱ) on D201 resin were investigated. The effects of parameters including HCl concentrations, initial metal ion concentrations, contact time, and temperature on the adsorption of Pd(Ⅱ) were studied by batch method. The HCl concentration for studying the effects was set from 0.01 to 2 mol·L-1 and the optimal adsorption condition is in 0.01 mol·L-1 HCl solution. The adsorption isotherm of Pd(Ⅱ) on D201 resin was determined and the equilibrium data fitted the Langmuir model better than the Freundlich model. The maximum uptake capacity of Pd(Ⅱ) was 253 mg·g-1 at 298 K. The adsorption could be best described by the liquid film diffusion model. The enthalpy variation (ΔH) and entropy change (ΔS) of adsorption were equal to 2.49 kJ·mol-1 and 74.8 J·(mol·K)-1 respectively, indicating that the adsorption was endothermic in nature. Furthermore, the negative value of ΔG showed that movement of adsorbate from the solution to adsorbent surface was a spontaneous process. Pd(Ⅱ) could be eluted with 0.5 mol·L-1 HNO 3 solution. Thomas model was applied to experimental column data to determine the characteristic parameters of the column useful for process design. | XIONG Chunhua ZHU Shan YAO Caiping CHEN Qing | 2011 | Rare Metals2011，30，5： | 6 |

| 5 | Cloning of a novel gene associated with human nasopharyngeal carcinoma显示文摘One EST N27741 with high expression in normal adult nasopharynx tissues but low expression in adult poorly differentiated squamous nasopharyngeal carcinoma has been selected out by the high-density cDNA array expression profiling technique. The differential expression has been confirmed by RT-PCR. One novel gene of 1096 bp has been cloned based on this EST. Bioinformatics analysis found that the new gene sequence contains a whole reading frame encoding 256 amino acids. There is a stop codon TAA in front of the 5’ end start codon, and a tailing signal AATAAA and poly A tail at the 3’ end. There is no homologous known gene found after searching by blasting this sequence to non-redundancy nucleotide database. Therefore it is considered a novel gene related to nasopharyngeal carcinoma. | Zhiwei He Lu Xie Liangguo Xu Ke Lan Weidong Liu Ling Zhang Caiping Ren Jianling Shi Wen Zhou Kaitai Yao | 2000 | Chinese Science Bulletin2000，45，24： | 2 |
| 6 | Profiling gene expression patterns of nasopharyngeal carcinoma and normal nasopharynx tissues with cDNA microarray显示文摘5 μg of total RNAs from normal nasopharynx and nasopharyngeal carcinoma tissue have been labeled with α-32P-dCTP during reverse transcription. The synthesized cDNA probes have been hybridized to high-density cDNA microarray containing 5184 genes or expression sequence tags (ESTs). Then image analysis software has been applied to comparing their expression profiles. Results show that 187 ESTs were of density value above 200 in nasopharyngeal carcinoma tissue while there were 307 such ESTs in normal nasopharynx tissue; 38 ESTs were strongly expressed in nasopharynx, but weakly expressed in nasopharyngeal carcinoma; 48 ESTs were strongly expressed in nasopharyngeal carcinoma, but weakly expressed in normal nasopharynx. These results suggest that there may exist some new differentially expressed genes involved in nasopharyngeal carcinoma development. Furthermore, the results strongly indicate that high-density cDNA microarray is a powerful and efficient tool for large-scale screening differentially | Zhiwei He Caiping Ren Liangguo Xu Weidong Liu Lu Xie Zhongkui Li Kaitai Yao | 2000 | Chinese Science Bulletin2000，45，9： | 2 |
