摘要：Activated carbon prepared using natural rubber seeds for removing methylene blue. To estimate the interaction of adsorbates towards the adsorbent in this study applied adsorption studies. Freundlich and Langmuir isotherm has been used to predict adsorption model in this work. The study appeal two mechanism of radiation carbon,conventional and microwave heating,with various of impregnation ratio,adsorbent mass and radiation time. Carbon was activated by using various of KOH using conventional and microwave heating. The best yield was shown by activated carbon which dried using microwave heating in IR 1:1.5. The percentage of adsorption and qe value were 3.486 mg/g and 69.72%,respectively. The best result of adsorption MB using various of mass adsorbent was shown in 0.4 gr. The percentage was 90.24%. The Langmuir isotherm was suitable to this work,the n value was 0.5338. This study was well fitted with the pseudo-second-order. The calculation of qe(exp) was approach to the qe (cal) in pseudo second order..
