Testing of modified Iontosorb resins for its use in diffusive gradient in thin films technique
Szkandera, Roman ; Řezáčová, Veronika (referee) ; Diviš, Pavel (advisor)
6-mercaptopurine was joined by diazotation and copulation reactions on Iontosorb AV. Presence of thiol groups in modified resin was showed by infrared spectrometry. Amount of thiol groups was determined by iodometric titration. Resin gel was preparated from modified resin and agarose and both of them were tested for mercury determination by DGT technique.
