The Crystal Structure of the Ba-Hexacelsian Phases Doped with Ca2+ and Pb2+
(Springer International Publishing Ag, Cham, 2017)
The ion-exchange procedure is used for doping the Ba-hexacelsian structure with Ca2+ and Pb2+ cations. The hexacelsian doped with Ca2+ has a composition of Ba0.64Ca0.36Al2Si2O8, and hexacelsian doped with Pb2+ has a ...
Uticaj pH vrednosti na biosorpciju jona bakra otpadnom lignoceluloznom masom koštice breskve / Influence of pH value on cu(II) biosorption by lignocellulose peach shell waste material
(Savez hemijskih inženjera, Beograd, 2013)
Jedan od glavnih faktora u procesu biosorpcije predstavlja pH vrednost rastvora sorbata, jer istovremeno utiče na hemijsko ponašanje prisutnih kontaminanata kao i na aktivnost funkcionalnih grupa biosorbenta. U ovom radu ...
