ACTIVATED CARBON PREPARED FROM COCONUT SHELL POWDER WITH LOW ACTIVATION TIME AS SUPERCAPACITOR ELECTRODES

Treatment of Brewery Wastewater Effluent Using Activated Carbon Prepared from Coconut Shell

The use and effectiveness of granular and powder activated carbon made from agricultural waste (coconut shell) in the removal of organic matter in wastewater effluents from a brewery industry were investigated. The effect of process variables such as carbonisation temperature, carbonisation duration and activation temperature on the production and quality of activated carbon was studied. Experi...

Removal of Bi (III) with adsorption technique using coconut shell activated carbon as a low cost adsorbent

Removal of Heavy Metals from Dye Effluent Using Activated Carbon Produced from Coconut Shell

The ability of activated carbon produced from coconut shell to remoe mercury Hg (II), Lead Pb (II) and Copper Cu (II) from dye effluent was investigated. The activated carbon was produced through chemical activation processes by using zinc chloride (ZnCl2). The adsorption capacity was determined as a function of adsorbent dosage. The adsorption Isotherms of the studied metals on adsorbent were ...

Highly deformation-tolerant carbon nanotube sponges as supercapacitor electrodes.

Developing flexible and deformable supercapacitor electrodes based on porous materials is of high interest in energy related fields. Here, we show that carbon nanotube sponges, consisting of highly porous conductive networks, can serve as compressible and deformation-tolerant supercapacitor electrodes in aqueous or organic electrolytes. In aqueous electrolytes, the sponges maintain a similar sp...

Removal of Congo red dye from aqueous solutions by a low-cost adsorbent: activated carbon prepared from Aloe vera leaves shell

Background: Synthetic dyes have several harmful effects on human health as well as aquatic life. In this study, activated carbon (AV-AC), based on Aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of Congo red (CR) as a carcinogenic dye from aqueous solutions. Methods: In the batch system, the influence of different paramete...
