The adsorption and electroadsorption of bromide from natural water has been studied in a filter-press electrochemical cell using commercial granular activated carbon as the adsorbent. During experiments, different voltages were applied (2 V, 3 V 4 V) under anodic conditions. presence electric field improves capacity carbon. decrease concentration observed at high potentials (3 or may be due to ...

this study focus on the preparation of two supports including activated carbon derived from medlar and palladium nanoparticles loaded on activated carbon (pd-np-ac). subsequently, both adsorbent modified with a novel schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. the method is based on c...

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...

The process by which progesterone in an ethanol solution is retained by Merck granular activated carbon involves a reversible mechanism that conforms to a kinetic equation of unity partial order in both the progesterone concentration in solution, the coverage fraction (θ ) of the adsorbing surface and (1−θ ). Over the temperature range 10–40◦C, the specific adsorption rate varies from 5.8·10−5 ...

Activated carbon prepared form coconut residues (CORC), and agricultural waste byproduct obtained after oil extraction was used for the adsorption of Ni(II) form aqueous solution. The process of uptake obeys both Freundlich and Langmuir adsorption isotherms. Kinetic studies indicate that it obeys Lagergram kinetic model. Quantitative removal of Ni(II) from 100mL aqueous solution containing 10mg...

Spectrophotometric measurement applied on saturated granular activated carbon (GAC) is not yet explored. A colorimetric method in the visible range has been developed in order to determine the exhaustion level of GAC used in rum production. Aqueous ammonia solution has been used as an indicative agent to determine the extraction rate of taste compounds within the rum production process and the ...
