Abstract

This study aims to determine the equilibrium model and adsorption kinetics of methylene blue (MB) solution using kluwak shell carbon (KTK) both activated and without activation. Equilibrium adsorption was carried out on a volume of 50 ml of methylene blue at 9 concentrations of MB 80, 90, 100, 110, 120, 125, 130, 140 and 150 ppm, 0.15 g KTK, 90 min with a shaker speed of 300 rpm. Process kinetics, volume 400 ml concentration of 100 ppm, 1.2 g KTK, MB for 105 minutes, sampling interval 15 min, stirrer speed 300 rpm. The adsorption equilibrium model are Freundlich and Langmuir, while the kinetic model are Pseudo First Order and Pseudo Second Order. Determination of both the equilibrium and kinetic models are determined by the larger correlation coefficient (R2 ). The calculation of these two models are based on the equilibrium concentration (Ce) and a certain time concentration (Ct) measured using UV-VIS at a wavelength of 662 nm, the absorbance is converted to Ce or Ct with the standard curve equation MB. The results showed that the equilibrium adsorption and kinetics of MB using KTK and KTK 3M KOH followed the Langmuir equilibrium .. .. , R2 0.8020 and kinetics .∗ .². .. .∗ .² . 𝑡 , R2 0.9853 at unactivated KTK.
