AN ANALYSIS OF PB(II) ION REMOVAL FROM AQUEOUS SOLUTIONS EMPLOYING VARIOUS IRON TITANATE (FETIO3) NANOPARTICLE COMPOSITIONS

Iron titanate (FeTiO3) nanoparticles were synthesised with three distinct Ti weight percentages and a constant Fe weight. These characterised nanoparticles were utilised as adsorbents to extract lead (II) from aqueous solutions. An atomic absorption spectrophotometer (AAS) was used to estimate the percentage of ion elimination. In all investigations, FeTi-2.0 NPs showed efficient adsorption behaviour (SBET =199.1 m2g -1) for the removal of Pb (II) ions. The Nano catalyst had the highest adsorption capacity (qe, mg/g) in the Freundlich adsorption isotherm, and when the temperature (K) increased, the highest adsorption capacity was seen at 333 K (60°C). The adsorption process was found to be spontaneous and endothermic (∆Go = -8.43 kJ/mole; ∆Ho = 7.88 kJ/mole) under established conditions.
