韩国铁路大罢工背后的博弈简

刚刚过去的2013年,韩国经历了历史上为期最长的铁路工会罢工事件。12月9日,韩国铁路工会开始罢工,其目的在于抗议韩国铁道公社和政府以设立水西KTX（韩国高速铁路）股份公司为手段实现铁路民营化。10日,韩国铁道公社召开理事会会议,表决通过设立水西KTX法人公司运营从首尔市江南区水西站始发高铁的有关事宜。     

Adsorption studies of tannic acid by commercial ester resin XAD-7

<正>Tannic acid and its related compounds are known as refractory organic pollutants,and it can create serious problems for the environment.The adsorption and desorption studies of tannic acid on commercial resins XAD-7 and D-201 are performed,and all data indicates resin XAD-7 can be used as an effective adsorbent for removing tannic acid during water/wastewater treatment.Furthermore,adsorption thermodynamics studies indicate different adsorption mechanisms for TA on XAD-7 and D-201.FT-IR and solid state ~(13)C-NMR spectroscopy are used to explain the adsorption force between XAD-7 and TA.It suggests that hydrogen bonding is the main adsorption force for TA.Finally,XAD-7's adsorption capacity in the presence of different metal ions is investigated,which indicates that heavy metal ions in solutions can decrease the adsorption capacity for TA on ester resin XAD-7.
