High Efficiency of the Removal Process of Pb(II) and Cu(II) Ions with the Use of Fly Ash from Incineration of Sunflower and Wood Waste Using the CFBC Technology

In these research studies, fly ash (SW-FA) resulting from the incineration of sunflower (20%) and wood (80%) waste employing circulating fluidized bed combustion (CFBC) technology was used to analyze possibility removing Pb(II) Cu(II) ions in adsorption processes. Currently, great emphasis is placed on circular economy, zero or climate neutrality strategies. The use low-cost SW-FA seems fit well with pro-ecological, economic energy-saving trends. Hence, this material characterized by various techniques, such as granulation analysis, bulk density, SEM-EDX, XRD XRF BET, BJH, thermogravimetry, zeta potential, SEM morphology FT-IR spectrometry. As a result conducted research, factors influencing effectiveness process, adsorbent dosage, initial equilibrium pH, metal concentration contact time, were analyzed. maximum removal efficiency achieved at level 99.8% for 99.6% Cu(II), respectively. kinetics analysis isotherms showed that pseudo-second-order equation Freundlich isotherm models better describe experiments proved can act an appropriate highly effective lead copper wastewater improvement water quality.
