Natural Mesoporous Activated Carbon from Toxic Plant Stellera Chamaejasme Roots by Chemical Methods
Year: 2018
Type: article
Abstract: Stellera chamaejasme, widely distributed on the Qinghai-Tibet Plateau, is a poisonous plant causing serious harm to grassland. Activated carbons have been prepared from the roots of Stellera chamaejasme via phosphoric acid and zinc chloride activation at500℃ for 60 min with an impregnation ratio of 3:1. Yield (25.1% -27.6%), ash (4.5%-4.9%), methylene blue (195.0 mg/g-254.5 mg/g), iodine value (720.4 mg/g-810.5 mg/g), specific surface area (1023.3 m2/g-1216.7 m2/g), specific pore volume (2.13 cm3/g-2.26 cm3/g), mesopore volume (1.30 cm3/g-1.59 cm3/g) and average pore size (5.88nm-7.45 nm) of the products were determined. The results from both the zinc chloride and phosphoric acid activation processes showed that the activated carbons of S. chamaejasme roots exhibit a characterization of natural developed mesopores.
