Abstract
There is provided an activated carbon having a high total trihalomethane filtration capacity, even in water treatment by passing water at a high superficial velocity (SV). In the activated carbon of the present invention, a pore volume A of pores with a size of 1.0 nm or less, of pore volumes calculated by the QSDFT method, is 0.3 cc/g or more, and a pore volume B of pores with a size of 3.0 nm or more and 3.5 nm or less, of pore volumes calculated by the QSDFT method, is 0.009 cc/g or more.
Claims7
An activated carbon in which a pore volume A of pores with a size of 1.0 nm or less, of pore volumes calculated by the Quenched Solid Density Functional Theory (QSDFT) method, is between 0.30 and 0.50 cc/g, and
- a pore volume B of pores with a size of 3.0 nm or more and 3.5 nm or less, of pore volumes calculated by the Quenched Solid Density Functional Theory (QSDFT) method, is between 0.009 and 0.025 cc/g.
