Determination of parameters affecting kinetic and thermodynamic values for lead removal using wastewater treatment plant sewage sludge ash
Özet
In this study, treatment of lead containing wastewater using sewage sludge ash obtained from the
incineration unit in the domestic wastewater treatment plant in Gaziantep province in Turkey was investigated. The
main purpose of the study is to determine the potential of using the treatment sludge ash, which comes out as waste
in the treatment plant, in the treatment of wastewater of another industry. As a result of this study, the most suitable
adsorption conditions were determined and focused on the kinetics of adsorption. In the experiments, the lead
adsorption capacity of sewage sludge ash was determined as 122 mg g-1 at 0.5 g L-1 adsorbent concentration in
wastewater containing 100 mg L-1 Pb2+ under optimum conditions. As a result of the research, it was determined that
the adsorption reaction proceeds according to the pseudo second degree reaction and is suitable for the Langmuir
isotherm. As thermodynamic constants, ΔH° = 7.407 kJ mol-1 and ΔS° = 33.25 J mol-1 were determined. As a result
of this, it was determined that the adsorption reaction was endothermic, spontaneous and random, and adsorption
was physical adsorption. The results show that sewage sludge ash can be used in the treatment of water containing
high concentrations of Pb2+.
