Activated carbon

The use of low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. Orange peel was collected from the local fields of orange trees and converted into a low-cost adsorbent. The present study deals with the r

Activated carbon was prepared from hazelnut husks with zinc chloride activation at 973 K in nitrogen atmosphere. BET surface area of the activated carbon was found 1092 m2g!1. The removal of Cu (II) and Pb (II) ions from aqueous solutions was studied by batch method. The effects of initial pH, conta

Bagasse pith, which is the main waste from sugarcane industry in Egypt, has been used as a raw material for the preparation of different activated carbons. Activated carbons were prepared from bagasse pith by chemical activation with 28% H3PO4 (AC1), 50% ZnCl2 (AC2) followed by pyrolysis at 600°C an

High efficiency activated carbon with different chemical characteristics, appropriate for the purification of waste and potable water with different pollutions (metal ions) was prepared. It was established that activated carbon is obtained from carbonized olive stones in presence of nitrogen in the

In this study, two activated carbons were prepared from loofa, loofa carbon-1 (LC1) and loofa carbon-2 (LC2). The surface structure of LC1 and LC2 were analyzed by scanning electronic microscopy (SEM). The ability of LC1 and LC2 to remove reactive orange (RO) dye from aqueous solutions by adsorption

Bamboo, indigenous to Hong Kong and China, is widely used as scaffolding in construction and building projects. However, over 50,000 tonnes of bamboo scaffolding waste is disposed as landfill waste each year. Nevertheless, these wastes can be used as raw materials for the production of a range of hi

Activated carbon was developed from coconut coir pith using ZnCl2 and investigated to assess the possible use of this adsorbent for the removal of sulfate from water. The influence of various parameters such as agitation time, sulfate concentration, adsorbent dose, pH and temperature has been studie

In this work, removal of acid orange 7 (AO7) by powdered activated carbon, from aqueous solutions with initial concentrations of 150 ppm to 350 ppm and initial pH values of 2.8, 5.8, 8.0 and 10.5 at 25°C was studied. Experiments were done in batch mode and the experimental solutions were agitated pe

In this work the performance of activated carbons prepared from raw and demineralised lignite for gas-phase Hg° removal was evaluated. A two-stage activation procedure was used for the production of the activated samples. In order to study the effect of mineral matter on pore structure development a

A bench scale submerged microfiltration system coupled with high concentration of PAC (powdered activated carbon) was applied in order to purify a river water containing secondary effluent. The system was operated with four different modes: Run-1, -2, -3 and -4. The PAC concentration was set at 0, 4
