摘要: The powdered activated carbon (AC) supported by carbonaceous nano-adsorbents were examined to remove hexavalent chromium [Cr (VI)] from aqueous solution The adsorption behaviour of micro-level concentration of Cr (VI) on those nano-adsorbents was investigated as a function of the experimental conditions such as the contact time, the pH, the dosage of adsorbent, and the initial concentration of Cr (VI). The structural characterization of the adsorbents was accomplished by Fourier transform infrared spectroscopy and scanning …
