Energy transfer processes from Yb3+ to Ln3+ (Ln=Er or Tm) in heavy metal glassesA.Kos1,I.Czopek1,J.Pisarska1,W.A.Pisarski11. University of Silesia, Institute of Chemistry摘 要:Heavy metal glasses doubly doped with Yb3+ and Ln3+ ions(Ln=Er or Tm) were studied. Glass host matrices were limited to lead borate glass and lead germanate glass. Efficient......

; surfactant; dynamic light scattering; heavy metal 以废水回用和物质回收为目的的膜分离技术作为一种新型高效的水处理技术普遍受到国内外的关注.胶团强化超滤(Micellar enhanced ultrafiltration,MEUF)是一种表面活性剂和超滤相结合的技术,用于处理重金属离子废水.通常只能用纳滤或反渗透来截留金属离子,但这些技术存在通量低和费用高等缺... on metal removal were studied with anionic surfactant sodium dodecyl sulfate. The micelle sizes were determined by dynamic light scattering measurements. The results show that the micelle sizes......
extraction was achieved for each heavy metal as follows: 86% for Pb, 98% for Zn, 82% for Fe, 96% for Cd, 62% for Cu, 80% for Al, respectively. And the main compositions of the finally obtained solid... a fundamental study for systematic investigation on the application of hydrochloric acid to the leaching process of heavy metal from fly ash in present work. 2 Experimental 2.1 Source and analysis......
