This study investigates the influence of three carbon materials obtained from the explosion of acetylene gas on the adsorption performance of brilliant green dye. The Rosette like carbon (RLC) shows excellent adsorption properties and high reusability, making it an ideal substitute for existing carbon adsorbents.
This paper investigates the influence of the structure, composition, pore size distribution and morphology of three carbon materials obtained from the explosion of acetylene gas on the adsorption performance of brilliant green (BG) dye. During the process, Rosette like carbon (RLC) is obtained in the detonation reaction gas with small amount of ammonia. It shows excellent adsorption properties and high reusability. The adsorption capacity is more than twice of C-nN and C-pN at the concentration of BG of 100 mg/L, the maximum monolayer adsorption capacity of 357.32 mg/g, elimination efficiency can reach 88.5% after 10 cycles of adsorbing BG, which is the best adsorption performance among the currently reported carbon materials. The adsorption equilibrium accords with Langmuir isotherm model and falls into single molecular layer absorption. The temperature and pH value selected have little effect on its adsorption capacity. The excellent properties of RLC contribute to an ideal substitute to the existing adsorbents of carbon materials.
