Removal of chromium(III) ions was investigated using raw mandarin peel and activated carbon derived from it. The percentage removal of Cr 3+ ions was studied as a function of initial concentration of the heavy metal solution, pH and separation time. The results showed that the maximum percentage removal of chromium(III) of 67 % at 0.1 × 10 -3 mg/L by raw mandarin peel sample and 80 % at 0.025 × 10 -3 mg/ L by activated carbon sample, 73 % in alkaline media and 60 % in natural media by activated carbon and raw mandarin peel, respectively; and reached to 67 and 81 % after 30 min of separation time by raw mandarin peel and activated carbon, respectively. Further, the observation also showed an acceptable efficiency for the removal of Cr 3+ ions by the both adsorbents, particularly by activated carbon when compared to raw mandarin peel sample.

Abstract. The article addresses the urgent task of improving the adsorption capacity and expanding the scope of application for commonly used industrial sorbents -activated carbons and synthetic zeolites. Among a variety of methods for modifying these sorbents, more attention is now being given to techniques that employ carbon nanomaterials. This is due to the unique properties of nanostructures -developed surface, availability of active functional groups, etc. In the present work, the classic materials -NWC coconut shell activated carbon and synthetic NaX zeolite -were chosen as initial sorbent samples to be modified. The authors developed a process flowsheet for the carbon nanomodification, which contains the following main stages: preparation of a catalytic mixture solution under given temperature conditions, impregnation of porous materials using the obtained solution, and drying and synthesis of carbon nanotubes via chemical vapor deposition. The proposed technological line consists of a reactor for synthesis of carbon nanotubes, the patented design of which will allow for simultaneously modifying in an effective way different types of materials. As a result, the layer of carbon nanostructures, the quality of which can be varied by changing the conditions of the modification procedure, is formed on the substrate surface.

“…Zurairah (2015) uses waste palm shells and crab shell waste (Tachypleus gigas) for the preparation and characterization of CNT-chitosan nanocomposite with the composition ratio (1: 3) through the methods of sonication. Salam et al (2011) have added glutaraldehyde used as agents crosslinking the MWCNT-chitosan nanocomposite, and the result was applied as adsorbent with reviewing the influence of increased temperature, mass difference adsorbent, and the speed of the flow rate to attract heavy metals such as Co, Cd, Zn and Ni. From these studies, it is to obtain the maximum results in the adsorption levels of Hg in gold mining wastewater, it is necessary to modify the adsorbent that is by mixing MWCNT processed waste palm shells, chitosan and glutaraldehyde through sonication methods.…”
