Adsorption of naphthalene from aqueous solution on activated carbons obtained from bean pods.
The preparation of activated carbons from bean pods waste by chemical (K(2)CO(3)) and physical (water vapor) activation was investigated. The carbon prepared by chemical activation presented a more developed porous structure (surface area 1580 m(2) g(-1) and pore volume 0.809 cm(3) g(-1)) than the one obtained by water vapor activation (258 m(2) g(-1) and 0.206 cm(3) g(-1)). These carbons were ...
متن کاملRemoval of Methylene Blue from Waste Water Using Activated Carbon Prepared from Rice Husk
The possible utilization of rice husk activated carbon as an adsorbent for the removal of methylene blue dye from aqueous solutions has been investigated. In this study, activated carbons, prepared from low-cost rice husk by sulfuric acid and zinc chloride activation, were used as the adsorbent for the removal of methylene blue, a basic dye, from aqueous solutions. Effects of various experiment...
متن کاملRemoval of Surfactants from wastewater by Rice Husk
Surfactants are one of the major components (10- 18%) of detergents and household cleaning products and are used in high volumes in developed countries. In the present research work, the ability of rice husk as a low cost adsorbent for anionic and nonionic surfactants in wastewater has been studied. The maximum removal efficiency for anionic surfactants was 97%, in an aqueous solu...
متن کاملcharacterization and sodium sorption capacity of biochar and activated carbon prepared from rice husk
biochar and activated carbon, as carbon-rich porous materials, have wide environmental applications. in the present research, rice husk (rh) was used for preparation of biochar at 400, 600, and 800 °c under simple pyrolysis, physically-activated carbon with water steam, chemically-activated carbon with potassium hydroxide (koh), and physiochemically-activated carbon with koh and steam. physical...
متن کاملPb ADSORPTION FROM AQUEOUS SOLUTIONS ON ACTIVATED CARBONS OBTAINED FROM LIGNOCELLULOSIC RESIDUES
Activated carbons obtained from cane sugar bagasse (ACB), African palm pit (ACP) and sawdust (ACS) were prepared through an impregnated with HNO3 and thermal treatment in an atmosphere in N2/steam water at 1173 K. Adsorption isotherms of N2 at 77 K and of CO2 at 273 K were determined for the activated carbons for which surface area and pore volume values were from 868 to 1100 mg and from 0.27 t...
