摘要： A water-processing filter having a high dimensional accuracy and an improved filterability (such as a capability to remove turbidity components) is provided. The water-processing filter comprises (A) a hollow cylindrical filter which comprises (a1) a granular activated carbon having a median particle size of 30 to 80 μm and (a2) a fibrillated fibrous binder. The cylindrical filter (A) has an upstream outer surface having an arithmetical mean deviation of a waviness profile adjusted to not more than 30 μm and an arithmetical mean deviation of a primary profile adjusted to 35 to 45 μm. The cylindrical filter (A) may have a downstream inner surface having an arithmetical mean deviation of a waviness profile of not more than 30 μm and an arithmetical mean deviation of a primary profile of 35 to 45 μm. The cylindrical filter (A) may have a grounded outer surface. In a hollow space of the cylindrical filter (A), (B) a cylindrical filter comprising (b1) a granular activated carbon having a median particle size of 30 to 80 μm and (b2) a granular binder may be disposed.

摘要： In an activated carbon for adsorbing a noble metal from an aqueous solution containing the noble metal, the difference (absolute value) between a zeta-potential in a 10 mmol/L aqueous solution of sodium tetraborate and a zeta-potential in a 0.01 mmol/L aqueous solution of sodium tetraborate is adjusted to not more than 18 mV and the pore volume of pores with a pore radius of not more than 1 nm is adjusted to 150 to 500 mm3g. The activated carbon of the present invention may have a carbohydrate solution decolorizing performance of not less than 30%. The aqueous solution containing the noble metal may be a plating wastewater. According to the present invention, a noble metal can efficiently be adsorbed (or recovered) from a solution containing the noble metal.
