| 1 | Alkaline Hydrolysis to Reduce the AOX Concentrations in Effluents from Chlorination Treatment of Wool显示文摘Organic halogens generated in the chlorlnatlon treatment of wool are proven to be acutely toxic to human beings. Legislation on environmental pollution has become more and more stringent in recent years. So the chlorlnation treatment is faced with disuse. Alkaline hydrolysis is adopted to reduce the AOX (Absorbable Organic Halogen) concentrations in the effluents from the chlorlnatlontreatment under 40℃ and pH values 9, 10, 11 and 12. After treatment the reduction of AOX appears approximately 65%. | 朱泉 闫茹 | 1999 | Journal of China Textile University(English Edition)1999，16，1： | 0 |
| 2 | Butterfly and Nest-Shaped Tp*-W-Cu-S Cluster Monomers and Dimers with Hexamethylenetetramine as Ligand:Anion-Dependent Structures and Nonlinear Optical Properties显示文摘Main observation and conclusion The assembly of[Et4N][Tp*WS3](1)with CuX(Tp*=hydridotris(3,5-dimethylpyrazol-1-yl)borate;X=Cl,Br,andI)or[Cu(MeCN)][PF6]in the presence of tetratopic ligand hexamethylenetetramine(HMT)afforded an array of four cluster-based compounds,which are either neutral or anionic.These compounds include[Tp*WSzCu3Cl2(HMT)](2,monomer,neutral),[Tp*WSzCugBr2(HMT)](3,monomer,neutral),[Tp*WSzCu3l1 s(HMT)21(4,dimer,anionic),and[Tp*WSzCu2(HMT)]2(PFc)2(5,dimer,anionic).The size of the halogen is found to dictate the structures(2/3 versus 4),and the presence/absence of halogen also affects the utiliation of coordinate site of HMT(4 versus 5)by creating more available CuOite in the case of 5.The structures of 2-5 are also characterized using elemental analysis,Fourier-transform infrared(FT-IR)spectra,and ultraviolet-visible(UV-Vis)spectroscopy,with the dimeric structure of 5 also selected for the third-order nonlinear optical(NLO)property investigations.The NLO measurement results suggest that the hyperpola rizability value(v)of 5,reflecting its NLO properties as a neat material,features 2.12×10^(-30)esu,and it is comparable to other W/Cu/S clus-terbased molecular entities,rendering 5 a promising NLO-active material. | Quan Liu Mingie Lu Lice Yu Yinglin Song Jianping Lang | 2021 | Chinese Journal of Chemistry2021，39，3： | 0 |
| 3 | Regularities controlling the distribution of halogens in the Danzhai epithermal Hg-Au deposit in Guizhou and their significance显示文摘HALOGENS, as mineralizer elements, have been attracting ever increasing attention of geological workers inpetrogenetically experimental and ore-forming fluid geochemical studies. However, little research workhas been done on the contents, variation characteristics and significance of halogens in solid ores(rocks). It is found in the study of the Danzhai Hg-Au deposit that (i) variations in the contents ofhalogens and their distribution regularities in solid rocks and ores can shed light on the formation of thedeposit; and (ii) halogens can serve the function of indicator elements in search of buried orebodies. 1 Main characteristics of the ore | ZHANG Qian, PAN Jiayong and SHAO Shuxun Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China | 1999 | Chinese Science Bulletin1999，44，S2： | 0 |
| 4 | Tracer system on halogen mineralizer from the epithermal deposits in Guizhou Province显示文摘HALOGENS are typical mineralizer elements and play a very important role in remobilization and resettlement of the ore-forming mental elements in the hydrothermal deposits. Studies of tracer system on halogens mineralizer include the following aspects: (i) halogens’ role as mineralizer in ore-forming action;(ii) halogens importance as tracer elements in formation and evolution of the epithermal ore deposit;(iii) halogens’ significance as guidance in looking for the buried orebodies. Guizhou is a concentrated area of epithermal Hg, Sb and Au deposits, where are distributed famousepithermal deposits such as the Wanshan Hg deposit, the Banpo Sb deposit, the Danzhai Hg-Au depositand the Lannigou Au deposit. Many researches into geological and geochemical characteristics of thesedeposits have been done, but few study on halogen mineralizer. | PAN Jiayong, ZHANG Qian and SHAO Shuxun Open Laboratory of Ore Deposit Geochemistry, Geochemistry of Institute, Chinese Academy of Sciences, Guiyang 550002, China | 1999 | Chinese Science Bulletin1999，44，S2： | 0 |
| 5 | Preliminary measurements of boundary layer reactive halogens based on MAXDOAS technique over Salt Lake in West China显示文摘The reactive halogens play key roles in the destruction of boundary layer ozone by catalytic reactions and provide a fast pathway to the sedimentation of elemental gaseous mercury.The presence of bromine oxides in the | LUO Yuhan SI Fuqi DOU Ke ZHOU Haijin XIE Pinhua | 2014 | Acta Geologica Sinica(English Edition)2014，88，S1： | 0 |
