Synthesis of mesoporous silica microspheres larger than 10 microm via surfactant template approach has rarely been reported. According to the previous studies, particle morphologies were highly variable, depending on the synthesis conditions and impeller design such as impeller type, size, and agitation speed. A new robust surfactant-template synthesis strategy for the stable suspension of large silica microspheres was investigated by introducing an additional cosurfactant.

Large sample sizes of uranyl ions are eluted on a strenedivinylbenzene copolymer phase and an octadecyl phase column, respectively, using alpha-hydroxyisobutyric acid (alpha-HiBA) as an eluent. Chromatograms are obtained from variations of the uranyl sample amounts, eluent concentrations, concentrations of the sample matrix, and the pH of the sample solution for both columns, respectively. Column capacities are estimated from the loading factors measured from the retention times of the peaks.
