Phragmites australis activated carbon production to remove dissolved solids from irrigation water

Abstract

Due to the high ability of Iran for producingActivated Carbon and the Fact that (1) it is not produced in the power fromwith particle size of lower that 100 nm in the country, (2) to production inthe power from is not suitable, (3) high necessity for it and (4) its high inports to the country, the production of activated carbon with good adsorptionproperties are very important. For producing activated carbon, different rawmaterials need to be used. In the investigation study, cheap and availablephragmites australis were used. By physical activation, activated carbon wasproduced and then the effect of activated carbon on reducing dissolved solidwas investigated. Carbon and activated carbon samples of phragmites by usingpilot-scale furnace in the laboratory were produced. Additionally, the effectof each process variables such as adsorbent material (carbon and activatedcarbon), the mass of adsorbent and concentration of dissolve solids on theabsorption capacity, production efficiency and absorption properties of carbonand activated carbon were investigated. Then the optimum production conditionswere determined. The results showed that phragmites australis was cheapmaterial with suitable physical properties for activated carbon producing, andthat the activated carbon has higher adsorption capacity than carbon. For theremoval of dissolved from water.
