“…Powdered activated carbon is more efficient as compared to granular carbon owing to its extremely high surface area and hence the availability of more adsorption sites. In addition, an assortment of oxygen-containing surface functional groups also enhances the adsorption capacity [1,3].…”

“…Modified activated carbons have been successfully used in the past for the removal of toxic metals from aqueous solutions [3,8]. Nomanbhay found a maximum of 86% Cr (VI) removed by chitosan coated acid treated beads (CCAB) using its 13.5 g/L, while for chitosan coated beads (CCB) it was 64% at 18 g/L dosage and commercial activated carbon removed 52% at a dosage of 24 g/L [10].…”

Treatment of the contaminated aqueous solutions to improve their quality is indispensible for their reuse resulting in an emergent challenge to develop facile, nontoxic and less energy consuming techniques to purify water. Present study is therefore aimed at the synthesis of an adsorbent using agricultural waste i.e. coconut shell. The charcoal obtained from coconut shell was modified by acid activation and manganese doping following a simple chemical route. The products were characterized by scanning electron microscopy, energy dispersive X-ray analysis and infrared spectroscopy. Preliminary studies were carried out to compare the adsorption potential of acid modified coconut shell charcoal (AMCSC) and manganese doped coconut shell charcoal (MDCSC) for the removal of chromium (VI) and iron (III) from aqueous solutions. Various physicochemical parameters such as adsorbent dosage, initial metal ions concentration and pH were studied. MDCSC was found to be a better adsorbent for metals as compared to AMCSC and removed chromium more efficiently than iron from synthetic solutions i.e. 56.10% at optimum conditions i.e. 0.6 g/L adsorbent dosage, 10 mg/L initial metal ions concentration and pH = 3. The effect of adsorbents on color and conductivity of the aqueous solutions was also noted; slight variation in color of all the aqueous solutions with a maximum of 91.67% removal was observed.

/g), PE 바인더의 입자크기가 200 µm일 때 444 (m 2 /g), 20 µm일 때 940 (m 2 /g)로 측정되었으며, 필터 성능을 확인하기 위하여 염소 흡착 실험을 실시하여 정수 성능을 평가하였다. This paper describes activated carbon block filters prepared by extrusion for water purifier. The specific surface area of the activated carbon blocks affecting the properties of a polymer binder were investigated. Polyethylene (PE) particles were used as a binder polymer and the effect of particle sizes on changes in the specific surface area of activated carbon blocks in addition to the adsorption properties of chloride anion in the aqueous solution were investigated. The sizes and shapes of PE particles were measured using SEM. The specific surface area of activated carbon was 1186 m 2 /g. The specific surface area of PE binder was 444 m 2 /g and 940 m 2 /g with the particle sizes of 200 µm and 20 µm, respectively. In order to verify the performance of the filter, chlorine adsorption experiments were conducted.
