Characterisation of Activated Carbons Obtained from Rice Husk

Blog Article

Rice husk derived activated carbons doped with nitrogen have been studied using GOLDENROD SHAMPOO low temperature nitrogen adsorption, scanning electron microscopy, mercury porosimetry, thermogravimetric analysis combined with mass-spectrometry, differential scanning calorimetry and X-ray photoelectron spectroscopy.It has been shown that N-doped activated carbon produced by high temperature treatment of the starting material soaked with urea, has a significantly higher anion exchange capacity than the other samples studied, which correlates with its higher adsorption capacity towards nitrate ion removal from aqueous solutions with the initial concentration of 5 and Crevice Nozzle 15 ppm.
