1.Introduction In the past decade,metal-organic frameworks(MOFs) have received much attention as catalytic materials in addition to their applications in gas storage and separation due to their unique features,including their crystallinity,porous structure,huge specific surface area and the high density of open metal sites in the framework.Several studies on the catalytic activity of MOFs have shown their potential application to reactions like hydrogenation,isomerization,cyanosilylation,oxidation,Friedel-Crafts reaction,and condensation reactions [1,2].

人绒毛膜促性腺激素(human chorionic gonadotrophin,HCG)是由胎盘合体滋养层细胞分泌的一种糖蛋白类激素 [1].临床上检测血清或尿液中的HCG不仅可以作为妊娠以及胚胎发育情况判断的依据,更重要的是可以为妊娠疾病提供有力的辅助诊断支持.因此,对HCG 进行定量检测具有重要的意义.

内分泌干扰物已经成为一个全球性的环境问题.越来越多的证据表明这些污染物可以干扰人或动物体内正常激素调节的生理过程,引发生殖异常、神经及免疫毒性,致畸致癌等,严重威胁了我们的生存和繁衍.而值得注意的是,目前环境中已被证实的内分泌干扰物约有70余种,其中农药及其代谢物占60 ％以上.
纳米银的大量使用使其不可避免地进入环境之中.释放至环境中的纳米银可经过氯化与硫化过程转化为氯化银与硫化银.含纳米银纺织品在洗涤过程中,大部分纳米银可转化为氯化银[1].在废水处理厂,大部分纳米银可转化为硫化银并沉降至活性污泥中[2].
多溴联苯醚(polybrominated diphenyl ethers,PBDEs)是一种目前使用最广泛的溴代阻燃剂,具有疏水性、持久性和难降解性[1],易吸附于大气颗粒和沉积物中,由于该类污染物具有脂溶性高、水溶性低等特点[2],进入水体后易与有机质结合,成为此类污染物的重要归宿.
