摘要

Sorption is an effective method for uranium recovery from saline lake brines for the benefits of simplicity,rapidity and easy recycling.To make uranium extraction feasible,solid adsorbents which are effective under saline lake brine conditions should be developed.In present work,MCM-41 type silica adsorbents with different content of amidoximated groups were prepared via co-condensation method according to the following steps:1 g of CTAB was dissolved in 135 mL of deionized water and then 102 mL of ammonia was added to the solution.After stirring for 0.5 h,CTES and 5 mL of TEOS were mixed and added to the homogeneous solution.The mixture was stirred for 2 h at room temperature.
