HYDROGEN SULFIDE SEPARATION MATERIAL AND HYDROGEN SULFIDE SEPARATION MEMBRANE

摘要

To provide a hydrogen sulfide separation material which is useful for the production of a hydrogen sulfide separation membrane that has excellent hydrogen sulfide permeation performance (permeance) and hydrogen sulfide separation performance (selectivity). A hydrogen sulfide separation material which contains a water absorbent polymer and an amine-based carrier. In addition, this hydrogen sulfide separation material satisfies the condition expressed by formula (1) (X1-X2) × Y × 100/Z ≤ 0.1 (1) X1: the number of moles of an alkali metal contained in the water absorbent polymer X2: the number of equivalents of an ion exchange group contained in the water absorbent polymer Y: the average atomic weight of an alkali metal contained in the water absorbent polymer Z: the mass of the water absorbent polymer
