Abstract
U ovom završnom radu je ispitivana sorpcija bakrovih iona u šaržnom reaktoru primjenom prirodnog zeolita klinoptilolita. Pripremljene su otopine bakrovog(II) nitrata trihidrata različitih koncentracija. Koncentracije otopina su: 3,627 mmol dm-3, 8,203 mmol dm-3, 11,763 mmol dm-3, 20,661 mmol dm-3, 32,186 mmol dm-3, 40,746 mmol dm-3. Eksperiment je proveden miješanjem 0,5 g klinoptilolita i 0,1 dm3 otopine bakrovih iona različitih koncentracija uz trešnju pri brzini okretaja 200 okr min-1, stalnoj temperaturi od 298 K u trajanju od 72 sata. Uzorkovanje je provedeno nakon 24, 48 i 72 sata kako bi se uočila uspostava ravnoteže. Nakon miješanja, uzorci su se centrifugirali i filtrirali, a zatim je određena ravnotežna koncentracija bakrovih iona uz pomoć UV/VIS spektrofotometra. Matematička obrada rezultata je izvršena korištenjem matematičkog programskog paketa MATHCAD. Eksperimentalni podatci su uz mala odstupanja dali približno jednake rezultate za svaki od uzoraka. Učinkovitost sorpcije bakrovih iona je najbolja pri najnižoj koncentraciji otopine bakrovog(II) nitrata trihidrata, no dobivene vrijednosti su niže od očekivanih. Pretpostavlja se da je razlog dobivenim rezultatima manji broj aktivnih centara i visok udio nečistoća u klinoptilolitu.
Abstract (english)
In this bachelor thesis, the sorption of copper ions in batch reactor was investigated using natural zeolite clinoptilolite. Copper(II) nitrate trihydrate solutions of different concentrations were prepared: 3,627 mmol dm-3, 8,203 mmol dm-3, 11,763 mmol dm-3, 20,661 mmol dm-3, 32,186 mmol dm-3, and 40,746 mmol dm-3. The experiment was conducted by stirring 0,5 g of natural zeolite clinoptilolite and 0,1 dm3 solution of copper ions of different concentrations and shaking at stirring speed of 200 rpm, at a constant temperature of 298 K for 72 hours. Sampling was performed after 24, 48 and 72 hours in order to detect the establishment of equilibrium. After stirring, the samples were subjected to centrifugation and filtration, then the equilibrium concentration of the copper ions was determined by the UV/VIS spectrophotometer. Mathematical processing of the results was done using MATHCAD mathematical software package. Experimental data with slight deviations gave approximately the same results for each of the samples. The sorption efficiency of copper ions is best for the lowest concentration of copper(II) nitrate trihydrate solution, but the values obtained were lower than expected. It is assumed that the reason for the results obtained lies in a smaller number of active centres and because of high percentage of impurities present in clinoptilolite.
