Waste tire carbon adsorbent for active removal of paracetamol in aqueous solution

Abstract

Waste tyre carbon adsorbent was prepared via three different calcination temperatures (500°C, 700°C and 900°C) and activated by sodium hydroxide solution. The phase and crystallinity analysis of each adsorbent is determined using X-ray diffraction analysis. The study revealed that different crystallinity of prepared adsorbent were obtained when calcination temperature is varied. Next, the effect of calcination temperature was investigated on the removal of paracetamol in aqueous solution. The highest percentage removal (99.37%) was obtained when the waste tire carbon adsorbent is calcined at 900°C for paracetamol initial concentration of 10 mg/L at pH 3 and 120 mins of contact time. In this case, the result obtained can be contributed to the production of adsorbent using waste tire with suitable calcination temperature for the paracetamol removal in aqueous solution.
