Spectrophotometric determination of copper(II) in water with thiosemicarbazide

Adsorption of Cu (II) ions from water by carbon nanotubes oxidized with UV-light and ultrasonication

“…Before and after the adsorption process, Cu (II) ion concentrations were analyzed at UV-vis spectrophotometer (PG Instruments T60 model). The reagent for this analysis is thiosemicarbazide and the absorption maximum for Cu (II)-thiosemicarbazide complex is 356 nm [16]. The effects of amount of adsorbent results can be seen in Fig.…”
