Adsorption of 4-chlorophenol from wastewater-based activated carbon prepared from Jatropha seed husks

The removal of 4-chlorophenol (4-CP) from aqueous solution using activated carbon (AC8) prepared from Jatropha seed husks by potassium hydroxide as activating agent at 800°C was investigated. The AC8 was characterized by Fourier transform infrared spectroscopy and energy dispersive X-ray spectroscop...
