SBA-Pr-Imine-Furan as an environmental adsorbent of Pd(II) in aqueous solutions

<p>SBA-Pr-Imine-Furan, as an adsorbent, was prepared by the functionalization of SBA-Pr-NH₂ with furfural in 2 steps. The absorbent intensity of Pd²⁺ by SBA-Pr-Imine-Furan was studied by the atomic absorbance spectroscopy (AAS), which was demonstrated a high capacity to adsorb Pd(II) ions. Many factors affect the adsorbent, such as pH, the sample solution concentration, contact time, and the used eluent in optimized conditions. The maximum adsorption capacities of Pd(II) ion were found for SBA-Pr-Imine-Furan, was <strong>200</strong>&nbsp;mg g^&minus;1.</p>
