The present study was carried out to investigate the metal sorption potential of low-cost distillation sludges of caraway (DSC), basil (DSB), fennel (DSF), clove (DSCl), jasmine (DSJ); and immobilized distillation sludges of caraway (IDSC), basil (IDSB), fennel (IDSF), clove (IDSCl), and jasmine (IDSJ). The maximum equilibrium uptake of Pb(II) and Zn(II) ions was 0.80 and 0.30 mmol/g by IDSJ and IDSF, respectively. The optimum pH was 4.5 for Pb(II) and 6 for Zn(II). The optimum bead size was 3.5 mm. A slow decrease in Pb(II) and Zn(II) uptake was noticed with increase in shaking speed. The metal uptake capacity of Zn(II) sharply decreased with increase in temperature. Experiments revealed that sorption equilibrium reached much faster in case of textile industrial wastewater than synthetic effluents. Pseudo-first-order model fitted well to the kinetics data of Pb(II) at 30–50°C and of Zn(II) at 30–40°C. Metal uptake increased with increase in initial concentration of metal ions up to 200 mg/L. Acidic desorbents were found to be suitable as compared to EDTA in metal desorbing studies. [ABSTRACT FROM PUBLISHER]
