Description
Chufeng Cheng and coauthors build a 2026 material for pulling radioactive strontium out of water. Porous geopolymer beads served as a sturdy support for a crystal compound with strong strontium affinity. Heat based loading anchored the crystals evenly while keeping the pore channels open.
The composite removed about ninety two percent of strontium even in fairly acidic water. Plain beads removed almost none under the same conditions. Uptake capacity was high, and common sodium or potassium ions interfered little. Calcium and magnesium competed more strongly for the binding sites. Nuclear waste treatment gains a bead form that suits later flow through column testing.
