"EFFECT ACTIVATION OF CHEMICAL AND PHYSICAL TO STRUCTURE\r\nAND ACTIVATED CARBON QUALITY FROM CHARCOAL OBTAINED BY\r\nPYROLYSIS OF COCONUT SHELL"^^ . "Activation of coconut shell charcoal has been done by a combination of chemical\r\nand physical activation to determine the effect of chemical activators and activation\r\ntemperature to changes in the chemical structure and the quality of activated carbon .\r\nThe study was conducted on charcoal coconut shell of pyrolysis results with variation of\r\nconcentration and immersion time ZnCl2 as an activator , respectively 0.5 to 2 M for 12\r\nto 24 hours . Then proceed with the activation of physics in reactor the activation of the\r\ntemperature variation of 500 to 800 oC with CO2 gas flow rate 20 mL / min . Evaluation\r\nof the chemical structure and the quality of activated carbon performed FTIR , SEM ,\r\nspecific surface area , total pore volume , and average pore with Brunauer - Emmett -\r\nTeller ( BET ) . The results showed the results of the analysis of SPSS through\r\nCofficients test the concentration variables most affect to moisture content , ash content ,\r\nand iodine absorption from temperature variable and time of activation . The best quality\r\nactivated carbon produced at a concentration of ZnCl2 of 1.5 M, 24 hours soaking time of\r\n24 hours , temperature 800 oC and the activation time of 120 minutes . The results as\r\nmoisture content of 8.47 % , volatile matter content of 18.55 % , ash content 1.44 % ,\r\nbonded carbon content of 80.01 % and iodine absorption of 769.74 mg / g . The results\r\nof FTIR analysis showed the surface of activated carbon containing CO and CH bonds ,\r\nand SEM analysis showed the number and diameter of pores increased with the higher\r\ncalcination temperature . Surface area ( BET ) of 359.286 m2 / g , pore volume of 1.984 x\r\n10-1 cm3 / g and pore mean of 11.46 Ǻ ."^^ . "2014-05" . . . "Yogyakarta State University"^^ . . .
