Abstract
This study aimed to develop four adsorbents, neat and activated, from the cardoon leaves and stems. The developed adsorbents were first analyzed to determine the surface acid–base properties using Boehm’s method, pH at zero charge point, iodine and methylene blue values, and moisture, ash, and fixed carbon contents. They were also characterized by scanning electron microscopy coupled with energy-dispersive X-ray analysis, X-ray diffraction, Fourier transform infrared absorption spectroscopy, thermogravimetric analysis, and inductively coupled plasma atomic emission spectroscopy. After that, these adsorbents were applied for adsorption of an organic dye “brilliant green” (BG), and the effect of various parameters on the adsorption efficiency was evaluated. The obtained results revealed the differences between the adsorbents derived from the neat cardoon leaves and stems and their activated carbon in terms of properties and BG adsorption efficiency.
期刊介绍:
Open Chemistry is a peer-reviewed, open access journal that publishes original research, reviews and short communications in the fields of chemistry in an ongoing way. The central goal is to provide a hub for researchers working across all subjects to present their discoveries, and to be a forum for the discussion of the important issues in the field. The journal is the premier source for cutting edge research in fundamental chemistry and it provides high quality peer review services for its authors across the world. Moreover, it allows for libraries everywhere to avoid subscribing to multiple local publications, and to receive instead all the necessary chemistry research from a single source available to the entire scientific community.
