Recovery of Pd(II) Ions from Aqueous Solutions Using Activated Carbon Obtained in a Single-Stage Synthesis from Cherry Seeds

This paper describes a single-stage synthesis process for activated carbon using cherry seeds. The influences of the carbonization temperature and time were investigated. Using BET method, surface area obtained carbons was determined, as well pore distribution, while SEM images provided further insight into structure surface. Next, adsorption isotherm derived. For test, Pd(II) chloride complex ions used. It found that suitable palladium(II) recovery from diluted aqueous solutions. Out tested parameters synthesis, most optimal one to be 500 °C 3 h. Additionally, it confirmed increase in affects palladium load 1.6 mg/g at 20 15.6 50 (for best-performing sample). fact may suggest is associated with chemical reactions.
