| 1 | Catalytic Combustion of Diesel Soot over K_2NiF_4-type Oxides La_(2-x)K_xCuO_4显示文摘The K2NiF4 type oxides, La 2-x KxCuO4 complex oxides with nanometric size were prepared by sol-gel method. The characters of these samples were analyzed by H2-TPR, XRD, FT-IR and SEM. The catalytic activity for soot combustion was evaluated by temperature-programmed reaction (TPO) technique. The results demonstrate that the substitution of K+ for La 3+ at A-site will increase the catalytic activities of La 2-x KxCuO4 to soot combustion greatly, and the substitution quantity affects the structure and catalytic activity obviously. The La 1.8 K 0.2 CuO4 complex oxides with tetrahedral structure has the best catalytic activity for soot removal reaction, the ignition temperature of soot combustion is decreased from 490 to 320 ℃. | Zhu Ling Wang Xuezhong Liang Cunzhen | 2006 | Journal of Rare Earths2006，24，5： | 2 |
| 2 | Occurrence and health risk assessment of trace heavy metals via groundwater in Shizhuyuan Polymetallic Mine in Chenzhou City, China显示文摘Chenzhou 城市里的 Shizhuyuan Polymetallic 矿是在中国的重要多金属存款。在在 1985 的一个水坝事故以后,仍然在这个区域有很多采矿植物, smelters 和跟踪池溏。这些有潜力弄脏包围地下水。在这研究,地下水样品在干燥、湿的季节期间在这个区域从 20 口居民井被收集。特别地,这研究在地下水在暴露和对踪迹的健康风险评价上集中了重金属。多重统计分析和模糊全面方法被采用揭示重金属的分发特征并且估计地下水质量。结果显示了那 Cr, Fe, Ni, Cu, Zn,同样 Cd, Ba, Hg 和 Pb 与低暴露层次是普遍的。与在旱季的中等水平暴露很好有有低级暴露和暴露的 19 口井。所有井在湿季节期间在低级暴露。作为并且 Mn 展出了潜在的 noncarcinogenic 担心,因为他们的最大的危险商(HQ ) 比 1.0 高。这可以在两个季节在旱季或在孩子上在成年人上引起不利健康效果。尽管仅仅,证明最大的 carcinogenic 风险是超过 10 < 啜 class= “ a-plus-plus ” > 在干燥、湿的季节为孩子建议高癌症风险的 4 , 。因此,分析和减小集中作为并且在地下水的 Mn 被需要以便在区域保护居民和特别孩子的健康。 | Bingbing XU Qiujin XU Cunzhen LIANG Li LI Lijia JIANG | 2015 | Frontiers of Environmental Science & Engineering2015，9，3： | 2 |

| 5 | Efect of operating parameters on sulfide biotransformation to sulfur显示文摘A laboratory-scale bioreactor with polyethylene semi-soft packing was constructed and utilized to determine the efciency of sulfide biotransformation to sulfur under various operating parameters. Sodium sulfide dissolved in tap water was pumped into the bioreactor as sulfide for biological desulfurization. The sulfide, sulfur and sulfate-S in the efuent and the sulfide purged as gas-phase H2 S were determined to investigate the efects of operating parameters, such as pH, DO, hydraulic retention time(HRT), temperature and salinity, on the sulfide oxidation products. The activity of bacteria was highest at pH 7.8–8.2. The maximal sulfide removal load was 7.25 kg/(m3·day), with a 322.07 mg/L influent sulfide concentration and 4.80 mg/L DO. The increase of DO value corresponds to a decrease in the sulfur yield. The reactor had the highest sulfide removal load and sulfur yield at 2.55 mg/L DO. HRT had little efect on desulfurization efciency when the sulfide removal load was kept constant. The most efective desulfurization temperature was 33℃. The sulfide removal load decreased from 2.85 to 0.51 kg/(m3·day) with increasing salinity from 0.5% to 2.5%(m/m). | Weiguo Liu Cunzhen Liang Jiaqing Chen Ling Zhu | 2013 | Journal of Environmental Sciences2013，25，12： | 1 |
