The potential to remove Pb 2+ ion from aqueous solutions using the shells of hazelnut (HNS) (Corylus avellana) and almond (AS) (Prunus dulcis) through biosorption was investigated in batch experiments. The main parameters influencing Pb 2+ ion sorption on HNS and AS were: initial metal ion concentration, amount of adsorbent, contact time and pH value of solution. The influences of...
The objective of this study was to compare fly ash and activated carbon for their ability to remove nickel [Ni(II)] and zinc [Zn(II)] from an aqueous solution. The effects of contact time, pH, initial metal concentration and amount of adsorbent on the adsorption process at 20±2°C were studied. Batch kinetic studies showed that an equilibrium time of 1h was required for the adsorption of Ni(II) and...
