Acid Activated Bamboo-Type Carbon Nanotubes and Cup-Stacked-Type Carbon Nanostructures as Adsorbent Materials: Cadmium Removal from Water
Considerable amounts of heavy metals have been discharged to the environment since the beginning of the industrialization. Consequently, the concentration of toxic metals in rivers, lakes and oceans has increased notably. Cadmium, arsenic, copper, zinc, lead and other metals have been listed by the USEPA as the most common contaminants in wastewaters. Cadmium, in particular, has been identified...
متن کاملRole of activated carbon from natural adsorbent for removal of textile dyes: effect of pH, kinetic and adsorbent mass
In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

This paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using Persian mesquite grain. Several techniques and methodologies such as, proximate analysis, N2 adsorption–desorption isotherms, scanning electron microscope (SEM), Fourier transform infrared spectroscopy(FT-IR), X-ray Diffraction (XRD), X-ray photoe...
متن کاملActivated Carbon from Olive Wastes as an Adsorbent for Chromium Ions Removal
Adsorption of Chromium ions (VI) and (III) in aqueous solution was investigated using activated carbon prepared from olive wastes, by one step physical activation with steam. After adsorbent material characterization using adsorption capacity of methylene blue, iodine and phenol, BET surface area, Fourier Transform InfraRed (FT-IR) spectroscopy, pHpzc, surface functions based on the Boehm m...
متن کاملPreparation and Characterization of Activated Carbon derived from olive stone as adsorbent for Congo Red
Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...
