Abstract
The main objective of the present invention is to provide a filter having excellent performance in removing fluorine-containing organic compounds even when the superficial velocity (SV) of water to be treated is high. A filter according to the present invention includes an activated carbon molded body containing activated carbon. Among pore volumes calculated by a QSDFT method, the activated carbon molded body has a pore volume A (cc/g) of at least 0.30 cc/g of pores having a pore diameter of 2.0 nm or less, and has a pore volume B (cc/g) of at least 0.01 cc/g of pores having a pore diameter of 3.0-3.5 nm.
Claims6
A filter comprising an activated carbon molded body containing activated carbon,
- wherein among pore volumes calculated by a QSDFT method, the activated carbon molded body has a pore volume A (cc/g) of 0.30 cc/g or more of pores having a pore diameter of 2.0 nm or less, and has a pore volume B (cc/g) of 0.01 cc/g or more of pores having a pore diameter in a range of 3.0 to 3.5 nm.
A method for removing a fluorine-containing organic compound, the method including a step of removing a fluorine-containing organic compound in water to be treated containing a fluorine-containing organic compound by passing the water to be treated through a filter including an activated carbon molded body containing activated carbon, in which among pore volumes calculated by a QSDFT method, the activated carbon molded body has a pore volume A (cc/g) of 0.30 cc/g or more of pores having a pore diameter of 2.0 nm or less, and has a pore volume B (cc/g) of 0.01 cc/g or more of pores having a pore diameter of 3.0 to 3.5 nm.
Use of a filter for removing a fluorine-containing organic compound in water to be treated, the filter including an activated carbon molded body containing activated carbon, in which among pore volumes calculated by a QSDFT method, the activated carbon molded body has a pore volume A (cc/g) of 0.30 cc/g or more of pores having a pore diameter of 2.0 nm or less, and has a pore volume B (cc/g) of 0.01 cc/g or more of pores having a pore diameter in a range of 3.0 to 3.5 nm.
Use of an activated carbon molded body for producing a fluorine-containing organic compound removing filter, the activated carbon molded body containing activated carbon, in which among pore volumes calculated by a QSDFT method, the activated carbon molded body has a pore volume A (cc/g) of 0.30 cc/g or more of pores having a pore diameter of 2.0 nm or less, and has a pore volume B (cc/g) of 0.01 cc/g or more of pores having a pore diameter in a range of 3.0 to 3.5 nm.
