Abstract :
Kombucha Scoby is a colony consisting of bacteria, yeast and cellulosic pellicle that present fantastic performances in various fields. In
addition to the anti-toxicity and antimicrobial specifications of Kombucha scoby, this unique colony can be used for waste water treatment
and removal of heavy metals. Herein, efficiency of graphene oxide/Fe3O4 nanoparticles (GO/Fe3O4) and Kombucha Scoby in the removal
of Pb(II) from synthetic wastewater were examined and compared. The characteristics of GO/Fe3O4 nanoparticles were analyzed using
FTIR and SEM. Moreover, the effect of significant parameters such as pH (1-7), temperature (10-60 °C) and amount of adsorbent (1-200
g l-1) on the removal of Pb(II) ion from aqueous solution was investigated. The maximum adsorption efficiency was obtained at a
temperature of 50 °C and adsorbent amount of 0.3 and 15 g using GO/Fe3O4 and Kombucha Scoby, respectively. Additionally, pHPZC
values of 6.1 and 6.2 were obtained for GO/Fe3O4 and Kombucha Scoby, respectively. The maximum adsorption efficiencies for GO/Fe3O4
and Kombucha Scoby were found to be 98.08 and 99.73%, respectively. Likewise, the adsorption isotherm behavior of Pb(II) on
adsorbents were investigated using Langmuir and Freundlich models. Achieved results showed that the Langmuir isotherm model is better
fitted with experimental data. Furthermore, the maximum adsorption capacities by Langmuir model for GO/Fe3O4 nanoparticles and
Kombucha Scoby were found to be about 114.9 and 126.6 mg/g, respectively. Generally, achieved results revealed that Kombucha Scoby,
which is a cost affordable colony, can remove Pb(II) ions from water better than GO/Fe3O4.
