Impact of SBT impeller speed on copper sorption on zeolite in a batch reactor : bachelor thesis

Ovim je radom ispitana kinetika sorpcije iona bakra na zeolitu NaX i utrošak snage miješanja pri četiri različite brzine vrtnje SBT miješala pri konstantnoj temperaturi suspenzije. Izvor iona bakra bila je otopina pripremljena otapanjem odgovarajuće mase Cu(NO 3 ) 2 ∙ 3H 2 O. Korištene su čestice zeolita NaX srednjeg promjera 0,0565 mm. Eksperimenti su provedeni u šaržnom reaktoru izrađenom od stakla opremljenome s razbijalima virova i SBT miješalom. Dobiveno vrlo dobro slaganje kinetičkih eksperimentalnih podataka s Blanchardovim, odnosno neslaganje istih s Weber -Morrisovim modelom, ukazuje da je reakcija najsporiji korak procesa, odnosno da ispitivana reakcija sorpcije iona bakra na zeolitu NaX prati kinetiku drugog reda.In this work, the sorption kinetics of copper ions on zeolite NaX and the mixing power consumption at four different SBT impellers speed and constant suspension temperature has been studied. The source of copper ions was a solution prepared by dissolving the appropriate mass of Cu(NO 3 ) 2 ∙ 3H 2 O. The zeolite NaX particles with a mean particle diameter of 0.0565 mm were used. The experiments were carried out in a glass batch reactor equipped with baffles and the SBT impeller. Very good agreement of the kinetic experimental data with Blanchard's and deviation from the Weber - Morris model were obtained indicating that the reaction is the slowest step of the process and that the reaction of copper ion sorption on zeolite NaX follows the second order kinetics
