Summary: | Tires are highly durable and non-biodegradable and have negative impacts of landfill disposal. Waste tire pyrolysis char was chemically activated using KOH for copper ions removal from aqueous solution. The scanning electron microscope, proximate analysis and x-ray fluoresce are confirmed that chemical activated of waste tire pyrolysis char took place. The adsorption result revealed that waste tire activated carbon (WTAC) was more effective than waste tire pyrolysis char (WTPC) on the removal of copper ions from aqueous solution. The optimum process variables were found to be suitable: pH of 5; adsorbent dosage of 0.25 g/100 mL; initial concentration of 400 mg/L; contact time of 100 min and temperature of 25°C. Adsorption isotherms studies revealed that the experimental data were best fitted with Freundlich isotherm model. Moreover, the adsorption kinetics was best fitted with pseudo-first order model. Adsorption thermodynamic parameter such as ∆H°, ∆G° and ∆S° were calculated and it was established that the process was exothermic spontaneous and randomness in nature. |
