文摘

•: Synergetic effect exists in U(VI) sequestration onto NZVI-D.
•: Diatomite as a support accelerated reduction of U(VI) into less soluble U(IV).
•: Diatomite as an adsorbent of Fe(II) produced in-situ promoted U(VI) reduction.
•: Diatomite as a scavenger for insoluble products increased the reactivity of NZVI.
