Abstrakt: Cigarettes supplied by the Royal Malaysia Customs Department (RMCD) Perlis have been used as precursors for activated carbon production due to the increasing number of cigarettes seized. The confiscated cigarettes were normally disposed through incineration and landfilling, which can cause environmental and health problems. Thus, this research focused on developing activated carbon (AC) from confiscated cigarettes for the removal of methylene blue (MB) dye. There were two different forms of AC successfully produced; activated carbon with KOH (AC KOH) and without KOH treatment (AC control). The study revealed that AC KOH had the strongest adsorption capacity at 800C due to the pore structures that affect the performance, 98.5% of the MB dye removal. However, when increasing the initial MB concentration, the adsorption of the MB dye become less effective. The adsorption model was evaluated by the Langmuir and Freundlich isotherms and it was found that the Langmuir isotherm suited better, defining it as a monolayer adsorption. It was demonstrated that AC with KOH at 800Cproduced a higher quality adsorbent with qm of 24.390 mg/g. [ABSTRACT FROM AUTHOR]
