Title:
SELECTIVE SCAVENGER, PREPARATION METHOD THEREFOR AND USE
Document Type and Number:
WIPO Patent Application WO/2024/067622
Kind Code:
A1
Abstract:
A selective scavenger, a preparation method therefor and the use. The selective scavenger contains a calcium-scandium bimetallic layered hydroxide and diatomite, the mass ratio of the diatomite to the calcium-scandium bimetallic layered hydroxide being ≥0.14, the chemical formula of the calcium-scandium bimetallic layered hydroxide being [CaxSc(OH)y]OH, x being 2-3 and y being 6-8. The selective scavenger has good selectivity with respect to thermally-stable salts and hydrogen phosphate radicals, and has a selective adsorption ratio of the hydrogen phosphate radicals to thermally-stable salt anions being ＞6000, thus achieving efficient separation of the thermally-stable salts and the hydrogen phosphate radicals, and has good stability, and can prolong the working period, being suitable for popularization in industry.
