Removal of bisphenol A from water using cyclodextrins

V diplomskem delu smo proučili možnosti odstranjevanja okoljskega onesnaževala bisfenola A iz raztopin. Za ta namen smo uporabili β-ciklodekstrin, ki lahko selektivno tvori vključitvene komplekse z mnogimi substancami. Za analizno metodo smo izbrali UV/VIS spektrofotometer, s katerim smo spremljali absorbanco pri valovni dolžini značilni za bisfenol A. V prvem sklopu smo se osredotočili na odstranjevanje bisfenola A z dodatki vodnih raztopin β-ciklodekstrina različnih koncentracij. V drugem delu smo β-ciklodekstrin vezali na netkan poliesterni material, ki smo ga dodajali v različnih količinah v raztopino bisfenola A. Rezultate analiznih meritev smo med seboj primerjali in prišli do zaključka, da se največ bisfenola A odstrani pri dodatku tekstilnega materiala z 12 % nanosom β-ciklodekstrina.In the graduation thesis the removal of environmental pollutant bisphenol A from the water solution have been tested. For this purpose we have used β-cyclodextrin, which can selectively form inclusion complexes with various substances. For the analytical method we have chosen a UV/VIS spectrophotometer, which was used to measure the absorbance at a wavelenght characteristic for bisphenol A. First we have focused on removing bisphenol A in the solution by adding water solutions of β-cyclodextrin of differrent concentrations. In the second part we have binded β-cyclodextrin on a non-woven polyester fabric, which was added in different quantities to the solution of bisphenol A. The results of analytical measurements were compared and we have come to the conclusion that most of bisphenol A was removed when textile material with 12 % application of β-cyclodextrin was added to the solution
