Extraction chromatography–electrodeposition(EC–ED) process to recover palladium from high-level liquid waste

引用

Nuclear Science and Techniques 2017年第12期28卷 209-219页

作者： Qing Zou Shuai Gu Rui-Qin Liu Shun-Yan Ning Yan-Liang Chen yue-zhou Wei School of Nuclear Science and Engineering Shanghai Jiao Tong University Innovation Center for Metal Resources Utilization and Environment Protection College of Resources and Metallurgy Guangxi University

The extraction chromatography–electrodeposition(EC–ED) process was proposed for the quantitative recovery of palladium from high-level liquid waste(HLLW) in this study. The process coupled the extraction chromatography method to obtain the decontamination of Pd(II) from HLLW with the electrochemical method to recover metallic palladium from the concentrated *** of Pd(II) from a nitric acid medium by extraction chromatography using iso Bu-BTP/SiO_2-P adsorbent and the electrochemical behavior of Pd(II) in nitric acid solution in the presence of thiourea(TU) were *** Bu-BTP/SiO_2-P exhibited a high selectivity for Pd(II)over other fission products(FPs), and Pd(II) could be desorbed by TU from loaded BTP/SiO_2-P. The adsorbent performed good stability against HNO_3 because the adsorption performance kept Pd(II) after extended contact with HNO_3 solution. The column experiment achieved the separation of Pd(II) from simulated HLLW *** electrochemical behavior of Pd(II) in palladium desorption solution containing TU and nitric acid was investigated at a platinum electrode by cyclic voltammetry. A weak reduction wave at-0.4 V was due to the reduction in Pd(II) to Pd(0), and the deposition process wasirreversible. In electrowinning experiments, a maximum of92% palladium could be obtained.

组蛋白翻译后修饰是重要的表观遗传调控方式,包括组蛋白甲基化、乙酰化、磷酸化和泛素化等,在真核生物的基因组DNA复制、损伤修复、基因转录等生物学过程中发挥着重要的作用.组蛋白H2A单泛素化修饰(H2Aub)在动植物中高度保守,通常与基因的转录抑制相关[1,2].组蛋白泛素化是可逆的,维持生物体内组蛋白泛素化的正常水平对正常生长发育至关重要.以往的研究表明,动植物中具有保守RING结构域的E3连接酶形成PRC1复合体,负责催化H2A的单泛素修饰[1,3].组蛋白H2A去泛素化需要去泛素蛋白酶催化,对调控染色质上的H2A泛素修饰水平具有重要作用.以往的研究已经在动物中弄清了H2A去泛素化的分子机制,然而对植物中组蛋白H2A去泛素化的分子机制知之甚少.

Evolution of the electrical contact of dynamic pantograph–catenary system

引用

Journal of Modern Transportation 2016年第2期24卷 132-138页

作者： Guangning Wu Wenfu Wei Guoqiang Gao Jie Wu yue zhou School of Electrical Engineering Southwest Jiaotong University

A good contact between the pantograph and catenary is critically important for the working reliability of electric trains, while the basic understanding on the electrical contact evolution during the pantograph--catenary system working is still ambiguous so far. In this paper, the evolution of electric contact was studied in respects of the contact resistance, temperature rise, and microstructure variation, based on a home-made pantograph-catenary simulation system. Pure carbon strips and copper alloy contact wires were used, and the experimental electrical current, sliding speed, and normal force were set as 80 A, 30 km/h, and 80 N, respectively. The contact resistance presented a fluctuation without obvious regularity, concentrating in the region of 25 and 50 mf~. Temperature rise of the contact point experienced a fast increase at the first several minutes and finally reached a steady state. The surface damage of carbon trips in microstructure analysis revealed a complicated interaction of the sliding friction, joule heating, and arc erosion.
