PROBLEM TO BE SOLVED: To provide a novel molding of clinoptilolite in which the ion exchange is easy, and the pore distribution is controlled.SOLUTION: A clinoptilolite molding is such that the volume of pore of 50-1,000 nm of a diameter to the total volume of pore of 3-250,000 nm of a diameter is at least 50%. It is desirable that the pressure resistance is at least 5 N and at most 50 N. |
