In this modern time, precious metals hold an important place in human life. Secondary resources, such as waste, have become an essential alternative source to supplant these precious metals. Ionic liquids (ILs) have demonstrated excellent performance in recovering precious metals. Immobilizing ILs onto a solid support such as mesoporous silica simultaneously diminishes the IL drawback, enhances support adsorption capacity, and improves reusability. Thus, chemically enhanced mesostructured silica nanoparticles with trioctylodecylphosphonium chloride (P8Cl_MSN) may provide a superior adsorbent for Pd(II) from an aqueous solution. P8Cl_MSN shows a high adsorption capacity in batch and fixed-bed adsorption, 264 and 213 mg g −1 , respectively. The adsorption Pd(II) fits with the Langmuir isotherm model (R 2 = 0.998) and is chemisorbed onto the P8Cl_MSN. Pd(II) adsorption fits (R 2 = 0.999) with the pseudo-second-order kinetic model. The continuous adsorption of Pd(II) fits (R 2 = ∼0.99) with the Thomas and Yoon−Nelson model. Pd(II) desorption (98%) is achieved using CS(NH 2 ) 2 in 100 min, and P8Cl_MSN also shows excellent reusability performance and selectivity.

Simple fixed bed models such as the Bohart-Adams and Thomas equations are often used to describe the breakthrough characteristics of water and air contaminant adsorption in fixed bed adsorbers. However, these popular models are confined to correlating highly symmetric breakthrough curves. The present study investigates the feasibility of using two probability distributions (normal and log-normal) to track asymmetric breakthrough curves for water and air contaminant adsorption in fixed bed columns (ciprofloxacin, ammonium, hydrogen chloride, and hydrogen sulfide). The normal and log-normal probability distributions provided accurate fits to the slightly asymmetric ciprofloxacin breakthrough curve. They also provided a good representation of the overall shape of the ammonium breakthrough curve, but failed to describe the leakage of ammonium during the initial period of column operation. The log-normal distribution was able to match the asymmetric HCI and H2S breakthrough curves. The normal distribution, by comparison, failed to describe these two asymmetric breakthrough curves.Because the log-normal distribution has a floating inflection point, it was much more successful in describing the asymmetric HCI and H2S breakthrough curves that were sharp initially and 2 then broadened significantly as the column approached saturation. The ability of the normal distribution to track such asymmetric breakthrough data was impeded by its invariant inflection point.
