Abstract
U radu je ispitan utjecaj početne pH vrijednosti otopine u rasponu pH o =2,52-8,15 na vezivanje mangana na prirodni (PZ) i Fe(III)-modificirani zeolit (FeZ) iz otopine početne koncentracije, c o (Mn)=4,680 mmol/L. Nakon uspostave ravnoteže, u filtratu su određene ravnotežne koncentracije mangana u otopini i ravnotežni pH e . Iz eksperimentalnih rezultata izračunata je količina vezanog mangana po gramu zeolita, q e i stupanj vezivanja, α. Rezultati ukazuju da količina vezanog mangana, q e i stupanj vezivanja, α rastu s porastom pH o vrijednosti otopine. Maksimalna količina vezanog mangana u iznosu 0,040 mmol Mn/g PZ je u području 6,10<pH<8,15, odnosno 0,210 mmol Mn/g FeZ u području 4,01<pH<8,15. Navedeni raspon pH predstavlja optimalno pH područje za vezivanje mangana na zeolitne uzorke.
Abstract (english)
This paper investigate the influence of the initial pH of the solution in range pH o =2.52-8.15 on manganese removal onto natural (PZ) and Fe(III)-modified zeolite (FeZ) from the solution of the initial concentration, c o (Mn)=4.680 mmol/l. After equilibration, the concentrations of manganese as well as equilibrium pH e in supernatants are determined. From the experimental results the amount of sorbed manganese per gram of zeolite, q e and the sorption degree, α are calculated. Results indicate that the q e and α increase with increasing the solution pH. The maximum amount of sorbed manganese was 0.040 mmol Mn/g PZ in the range of 6.10<pH<8.15, and 0.210 mmol Mn/g FeZ in the range of 4.01<pH<8.15. The specified pH range is an optimum pH range for the sorption of manganese onto zeolite samples.
