Activated carbon, Tea residue, Physicochemical Properties, Wastewater treatment


The aim of this research was to study physicochemical properties of activated carbon prepared from tea residue on optimum conditions. The analysis included iodine number, apparent density, moisture content, volatile matter, ash content, carbon content. The study was done on morphology by SEM. The analysis of functional groups was conducted by FTIR technique. Investigation of elements in activated carbon was
done by XRF technique, and the crystal structure was studied by XRD technique. The effectiveness of wastewater treatment was tested with the sample from the canteen of Vongchavalitkul University, Nakhonratchasima Province. The result showed that activated carbon prepared from tea residue by carbonization at the temperature 500 °C for 120 minutes showed chemical characteristic O–H stretching and C–O stretching. The heat and chemical activation with 1: 2 ratios of charcoal: KOH at 800 °C had highest iodine number at 769.36 mg/g and apparent density of 0.63 g/cm3 which were in the criteria according to the characteristic defined by the Thai Industrial Standard (900-2004). In addition, the study on morphology showed that charcoal appearance of pore and activated carbon increased surface area and porosity. It was found that the specific position of carbonate function group, carboxylate (COO–) and lactose–CH2– (aliphatic structure of methylene and alkane) are major elements in the form of organic (C, H and O). The secondary components are inorganic elements of potassium (K) and calcium (Ca). Its structure was crystal and crystals of volatile compounds which was decomposed after carbonization, forming amorphous carbon. The effectiveness study of activated carbon prepared from tea residue for treatment of wastewater from the
canteen in the system of batch model found that the quantity of oil and fat decreased at 81.30%, followed by BOD 73.85% and suspended solids65.03%, respectively.
