Application of Low-Cost Sorbents for Removing Sulphates and Selected Metals from Water Matrix

Popis výsledku v původním jazyce

The adsorption of sulphates and selected metals (Cu, Mn, Fe) from water solution using orange peel was studied by means of batch mechanism. The aim of this study was to determine the dependency of sorption process on pH of the solution, the initial concentration of the sorbent, contact time and temperature. The Langmuier and Freundlich isothermal models were used to describe the sorption isotherms of ions. The Langmuier model is more suitable for describing data than that of Freundlich. The adsorption efficiency of removing copper (q20 = 5 mg/g) , manganese (q20 = 15 mg/g) and sulphates (q30 = 5 mg/g) by using orange peel was approximately 90%. Under optimal conditions, the efficiency of removing iron (q20 = 10 mg/g) was approximately 55%. When studying the kinetics it was discovered that the sorption process will follow the pseudo-second order. The thermodynamic parameters show exothermic character of sorption, and the processes will be spontaneous and favourable. FTIR analysis shows that the carboxyl and hydroxyl groups have participated in the sorption of ions. The results indicate that it is possible to use orange peel effectively for removing sulphates and selected metals from waste water. When adsorbing contaminants from aqueous solution by using wood decaying fungi (Fomitopsis pinicola), the effect of pH value, sorbent concentration, the initial concentrations of sulphates and metals (Cu, Mn,Fe), contact time and temperature were studied. Langmuier and Freundlich isothermal models were used to describe the sorption isotherms of ions. The Langmuier model describes the acquired data better than the Freundlich isotherms.
