摘要: Abstract Recently, titanate nanotubes (TNTs) have attracted more and attention in multidisciplinary areas because of their unique tube structure many outstanding physicochemical properties. This work examined the interaction U(VI) with TNTs as a function water quality factors such reaction time, medium pH, ionic strength, solid content, humic acid (HA) or fulvic (FA) by combined macroscopic spectroscopic investigation. The results indicated that was dependent on strength under acidic medium, while independent alkaline medium. Combined investigation, it is revealed outer-sphere surface complex inner-sphere can occur simultaneously during TNT sample. Besides, for first we found positive role HA FA at low pH values, whereas observed negative high values. Results be used an excellent adsorbent capturing from aqueous environments. Considering cost TNTs, conclude show great application potential disposal remediation U(VI)-contaminated wastewaters groundwater.
