Abstract
U ovom radu ispitan je utjecaj brzine vrtnje i pozicije PBT miješala na ionsku izmjenu bakra iz vodene otopine bakrovog(II) nitrata na sintetskom zeolitu NaX. Eksperiment se proveo u neprotočnom kotlastom reaktoru uz miješanje pri temperaturi od 27 °C. Ispitivan je utjecaj tri različite pozicije miješala pri čemu je omjer udaljenosti miješala od dna posude (C) i visine stupca kapljevine (H) u različitim eksperimentima iznosio 0,10; 0,33; 0,50. Određen je i iznos zakretnog momenta te izračunat utrošak snage (P). Analizom rezultata je uočeno da povećanjem C/H omjera raste i utrošak snage. Usporedbom eksperimentalnih podataka može se zaključiti da je najpotpunija ionska izmjena provedena pri C/H=0,33. Analizom eksperimentalnih rezultata utvrđeno je kako je proces izmjene iona u početnom periodu brz nakon čega usporava do uspostave ravnoteže. Kinetičkom analizom utvrđeno je da Ritchiev model pokazuje dobro slaganje s eksperimentalnim podatcima za sve tri pozicije miješala, dok s Weber-Morrisovim modelom nema slaganja, što znači da difuzija ne utječe na brzinu reakcije.
Abstract (english)
In this work the influence of the speed and position of the PBT impeller on ion exchange of copper ions from aqueous solutions of copper(II) nitrate on the synthetic zeolite NaX was investigated. The experiment was carried out in a batch reactor with stirring at 27 °C. The influence of three different positions of the impeller was tested, i.e. ratio of the distance of the impeller from the bottom of the vessel (C) to the liquid height (H) were C/H= 0.10; 0.33; 0.50. The amount of torque and mixing power consumption (P) were also determined, and analysed results showed that the increase in C/H ratio follows the increases of the power consumption. It was found that the optimal copper exchange was at C/H= 0.33.The analysed experimental results showed that in the initial period of the experiment the ion exchange process is faster. After, its speed decreases till the equilibrium is reached. The kinetic analysis established that the Ritchie model shows good fit with the experimental data for all three positions of the impeller, while there was no match with the Morris-Weber model which means that the speed of the process is not affected by diffusion.
