Removal of rhodamine B from aqueous solution by adsorption on corn cobs activated carbon
نویسندگان
چکیده
<p>In the present study, adsorption experiments were carried out to investigate removal of rhodamine B from an aqueous solution using chemically activated carbon corn cobs, a cheaper adsorbent. The characteristics determined X-ray diffraction, SEM, iodine number, pHpzc, and Boehm titration method. results show that prepared is amorphous, microporous, generally acidic on surface. kinetic study this was out, rate sorption found conform pseudo-second-order kinetics with 80 min as equilibrium time. revealed experimental data fitted better Langmuir isotherm model for removing B. interaction B-activated mainly chemisorption type. optimal conditions onto are mass = 0.3 g pH 3.15. maximum monolayer capacity be 5.92 mg.g<sup>-1</sup>. This has shown makes it possible effectively clean up wastewater contaminated by efficiency 99.60% 300 mg AC in 25 mL (5 mg.L<sup>-1</sup>).</p>

Removal of chromium (VI) from aqueous solution by adsorption using cousinia eryngioides boiss and activated carbon
Adsorption capacity of Cr (VI) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and found to be maximum at pH 2.0. The amounts of Cr (VI) adsorbed increased with increase...

Removal of Hexavalent Chromium Ions from Aqueous Solution by Adsorption Using Activated Carbon Prepared from Cucumis Melo Peel Activated carbon
Activated carbon prepared from Cucumis Melo Peel was used as adsorbent for the removal of chromium ion from aqueous solution. Adsorption experiments were performed by varying initial metal ion concentration, temperature, and pH. Freundlich and Langmuir isotherms were used to analyze the equilibrium data obtained at different adsorption conditions. Adsorption results obtained, shows that the Cr ...
