Abstract

The interaction of an aqueous solution of strontium nitrate with magnesium-doped potassium titanate nanotubes synthesized by coprecipitation followed by hydrothermal treatment is studied. It is found that after 2 h of exposure in the solution at room temperature, the composition with the replacement of 10 at % titanium by magnesium showed the greatest sorption capacity. The results obtained show the promise of using magnesium-doped potassium titanate nanotubes as adsorbents of strontium ions from aqueous solutions.

镁掺杂钛酸钾纳米管对锶离子的吸附

摘要

研究了硝酸锶水溶液与共沉淀和水热处理合成的镁掺杂钛酸钾纳米管的相互作用。发现在室温下在溶液中暴露2小时后，用镁代替10at％钛的组合物显示出最大的吸附容量。所得结果表明使用镁掺杂钛酸钾纳米管作为水溶液中锶离子吸附剂的前景。
