Abstract
U ovom radu je ispitan utjecaj četiri parametra na ionsku izmjenu bakra iz vodene otopine bakrova(II) sulfata na sintetskom zeolitu NaX u neprotočnom kotlastom reaktoru. Eksperimenti su planirani prema Taguchijevoj L9 ortogonalnoj matrici. Ispitivan je utjecaj veličine SBT miješala, brzine miješanja, vremena trajanja eksperimenta te veličine čestica zeolita NaX. Kako bi se pronašli optimalni uvjeti za vezanje maksimalne količine bakra na zeolitu NaX korištena je Taguchijeva analiza odnosno više-je-bolje pristup. Primijenjena metoda pokazala je da se maksimalno vezanje postiže kada se koristi miješalo od 8cm, brzina miješanja od 127 okretaja/min, vrijeme od 30 minuta te veličina čestica NaX zeolita od 50 do 71 μm. Osim što se ovom metodom mogu naći optimalni uvjeti ista omogućuje i definiranje utjecaja testnih parametara na proces, pri čemu je utvrđeno da najveći utjecaj na vezanje bakrovih iona na sintetskom zeolitu ima veličina čestica zeolita koju slijedi veličina SBT miješala, vrijeme te brzina miješanja. Osim Taguchijeve analize provedeno je i ispitivanje kinetike ionske izmjene s tim da je kinetika praćena pri optimalnim uvjetima prema Taguchijevoj analizi. Analizom eksperimentalnih rezultata utvrđeno je da je proces izmjene iona brz u početnom periodu nakon čega usporava do uspostave ravnoteže. Kinetičkom analizom utvrđeno je da jednako dobro slaganje pokazuju i Ritchiev i Blanchardov model.
Abstract (english)
In this work the influence of four parameters on ion exchange of copper ions from aqueous solutions of copper(II) sulphate on synthetic zeolite NaX in a batch reactor was investigated. Experiments were planned according to Taguchi's L9ortogonal matrix. The impact of SBT impeller size and speed, duration of experiment and particle size of zeolite NaX was investigated. Applied method, lager-is-better approach, has shown that the optimal copper exchange is at impeller size of 8 cm, impeller speed of 127 rpm, for 30 minutes and at particle size of 50 to 71 μm. Besides the optimum experimental conditions this method allowes to define the influence of each process variable on process conducted. It was found that particle size of NaX zeolite has the most significant influence on removal of copper ions on synthetic zeolite and is followed by impeller size, time and impeller speed. Copper kinetics has been studied by monitoring the amount of copper ions exchanged over time at optimum conditions according to Taguchi's analysis. Analysis of experimental results found that the ion exchange process is fast in the initial period and then decreases till equilibrium is reached. The kinetic analysis has found that both model used, Ritchie and Blanchard, show the same fit with experimental data.
