| 1 | Sr speciation in producing SrCO_3 with celestite显示文摘Strontium speciation transferring in strontium residue and mixing strontium ore are investigated with extracting experiment, X-ray powder diffraction(XRD), X-ray fluorescence spectrometer(XRF) and Atomic Absorption Spectroscopy(AAS). The results show that there are strontium carbonate, strontium sulfate, strontium sulfide, and a little amount of strontium silicate and strontium ferrite in strontium residue. Impurities in strontium residue mainly contain carbonate and oxide of calcium, iron, magnesium and aluminum etc. The amount of strontium sulfide in strontium residue is larger than that in strontium ore. And a little strontium silicate and strontium ferrite are found in strontium ore. It is concluded that acid soluble method is used firstly in the process of producing strontium carbonate from mixing strontium ore. In addition, mechanical smash method and surface active treatment to strontium samples are beneficial to the ratio-leaching increase of strontium. The research achievement helps to save energy and decrease pollutants emission in strontium processing industry. | LIU Chenglun ZHANG Li XU Longjun SU Zhimin XIE Taiping WANG Yuan | 2014 | Chinese Journal Of Geochemistry2014，33，3： | 2 |
| 2 | A joint call for actions to advance taxonomy in China显示文摘Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factordriven evaluation systems in China exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires,there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in China. | Chaodong Zhu Arong Luo Ming Bai Michael COrr Zhonge Hou Siqin Ge Jun Chen Yibo Hu Xuming Zhou Gexia Qiao Hongzhi Kong Limin Lu Xiaohua Jin Lei Cai Xinli Wei Ruilin Zhao Wei Miao Qingfeng Wang Zhongli Sha Qiang Lin Meng Qu Jianping Jiang Jiatang Li Jing Che Xuelong Jiang Xiaoyong Chen Lianming Gao Zongxin Ren Chunlei Xiang Shixiao Luo Donghui Wu Dong Liu Yanqiong Peng Tao Su Chenyang Cai Tianqi Zhu Wanzhi Cai Xingyue Liu Hu Li Huaijun Xue Zhen Ye Xuexin Chen Pu Tang Shujun Wei Hong Pang Qiang Xie Feng Zhang Feng Zhang Xianjin Peng Aibing Zhang Taiping Gao Changfa Zhou Chen Shao Libin Ma Zhaoming Wei Yunxia Luan Ziwei Yin Wu Dai Cong Wei Xiaolei Huang Jingxian Liu Xiangsheng Chen Tianci Yi Zhisheng Zhang Zhulidezi Aishan Qin Li Hongying Hu | 2022 | Zoological Systematics2022，47，3： | 1 |

| 4 | Preparation of Mn_3O_4 from low-grade rhodochrosite ore by chemical bath deposition method显示文摘Mn3O4was prepared with the chemical bath deposition(CBD) method. A Mn SO4 solution was obtained by the leaching and purifying of low-grade rhodochrosite ore(LGRO), which was used as raw material. The prepa ration procedures were studied and promoted. The result showed that the Mn3O4 with the highest purity and highes specific surface area could be obtained under the following processes. An Mn SO4 solution of 1.0 mol/L was added into a beaker under a flow rate of 30 m L/h. The p H of the reaction solution was adjusted to 10 using NH3 H2 O a80 °C. Then the solids were washed and dried at 200 °C fo2.5 h. The total Mn content(TMC) of Mn3O4 was 72.0 %The ionic distributions was formulated as [Mn2?[Mn2??0.3024Mn30.2937Mn4?h0.37860.0254]2O4. The average crys tallite size of Mn3O4 with a tetragonal hausmannite struc ture was found to be about 35 nm by X-ray diffraction(XRD) analysis. The BET specific surface area of the Mn3O4 measured was 32 m2/g. | Jing Zhao Longjun Xu Taiping Xie Chao Xie | 2015 | Chinese Journal Of Geochemistry2015，34，1： | 0 |
| 5 | Extraction kinetics of strontium with SDS and Twain in celestine显示文摘Strontium in celestine was activated in Twain-40 with the wetting and emulsifying methods. And strontium extract ratio increased providing that the negative effects of oxygen containing functional groups were eliminated on celestine surface. In the paper, the factors affecting the extraction of strontium in celestine were investigated with orthogonal experiments. The optimal conditions were described as follows: mass ratio of celestine to extracting aid=2.6:1, the solid-liquid ratio of extracting aid solvent composed was m(SDS): m(Twain 40): m(HCl)=6:1:2, when celestine was ground as small as less than 0.075mm in size, and extracted for 6 hours at 333K. The strontium extract ratio increased by 61.33% and reached 97.21%, while the ratio from the comparative experiment (without extracting aid agent) was only 35.88%. Extraction kinetics of strontium in celestine showed that the diffusion process was a controlling step, and the apparent active energy was about 14.1 kJ/mol. The research results were helpful to fully utilize strontium of celestine. | LIU Chenglun SU Zhimin XU Longjun ZHANG Li XIE Taiping WANG Yuan | 2013 | Chinese Journal Of Geochemistry2013，32，3： | 0 |
