Abstract
In this paper, a simulation study was performed for the use of mixed known adsorbents of zeolite and active carbon. Both adsorbents are well-known for their removal efficiency of organic (active carbon) and inorganic (zeolite) pollutants. A simulation based on experimental data using both adsorbents to remove a quaternary system of Cu2+, Pb2+, Ni2+ and crystal violet as an example of mixed organic and inorganic highly toxic pollutants was performed. Two types of low Si/Al ratio zeolites (i.e., LTA and FAU) were individually studied with active carbon. The program exhibited high prediction values that did not exceed an error of 6%. The use of this program may save time, money and experimental data, especially from an industrial standpoint. A complicated function of the selectivity for this mixture was fitted, and the results exhibited variability for different amounts of pollutants, as well as different amounts and ratios of adsorbents.
[Display omitted] 3 dimensional model for removal of quaternary system of Cu2+, Ni2+, Pb2+, and Crystal violet as a function of different ratios of zeolite/active carbon as simulated from our written program
•Organic and inorganic pollutants were studied over mixed composite of active carbon and zeolite.•Simulation study for above system were performed.•Program with complex calculation of partial selectivity including all pollutants was written.•A fitted synergetic functions was utilized for calculation of total amount removed or pollutants.•Program could reduce the effort and time for prediction of removal of such similar pollutants.
