Abstract
Due to the high ability of Iran for producing
Activated Carbon and the Fact that (1) it is not produced in the power from
with particle size of lower that 100 nm in the country, (2) to production in
the power from is not suitable, (3) high necessity for it and (4) its high in
ports to the country, the production of activated carbon with good adsorption
properties are very important. For producing activated carbon, different raw
materials need to be used. In the investigation study, cheap and available
phragmites australis were used. By physical activation, activated carbon was
produced and then the effect of activated carbon on reducing dissolved solid
was investigated. Carbon and activated carbon samples of phragmites by using
pilot-scale furnace in the laboratory were produced. Additionally, the effect
of each process variables such as adsorbent material (carbon and activated
carbon), the mass of adsorbent and concentration of dissolve solids on the
absorption capacity, production efficiency and absorption properties of carbon
and activated carbon were investigated. Then the optimum production conditions
were determined. The results showed that phragmites australis was cheap
material with suitable physical properties for activated carbon producing, and
that the activated carbon has higher adsorption capacity than carbon. For the
removal of dissolved from water.
