Adsorption of chromium from water by carbon nanotubes grown on powdered activated carbon

Lab-scale experiments were conducted and the adsorption of chromium (Cr) from aqueous solution by using carbon nanotubes (CNTs) grown on powdered activated carbon (PAC). The product is named PACNT. The effects of pH, PACNTs dosage, contact time and initial Cr concentration were studied at ambient ro...
