Abstract
In this study, the potential of Prosopis cineraria leaf ash (PCLA) as low-cost natural sorbent was evaluated for removing cadmium from aqueous solutions. Various operational factors such as adsorbent dosage, contact time, and solution pH were examined in batch adsorption tests. The Xray fluorescence spectroscopy (XRF) and Fourier transform infrared spectroscopy (FTIR) analysis were employed to characterize the PCLA sample. The maximum Cd (II) removal percentage of 96% occurred at initial pH of 7.0 and a PCLA dose of 3.0 g/L. The results indicated the pseudo second-order kinetic model showed the best accordance as a kinetic model. This work revealed that PCLA can be applied as effective and cheap adsorbent for cadmium removal from wastewater.
