摘要: Abstract In the present study, activation features of phosphoric acid have been investigated using waste peach stones as raw material in production granular activated carbon. Thermogravimetry/differential thermal analysis was conducted to characterize behavior stone and titration method used evaluate adsorption capacity produced It observed that iodine value carbon increased with temperature. However, temperatures higher than 500°C caused a destruction, which resulted decrease capacity. Activation longer 1.5 h at degradation porous structure The enhanced increasing amounts acid, however, excessive value. addition, it found yields generally decreased temperature activatio...
