Size tunable mesoporous carbon microspheres, MCMs were obtained using Pluronic F127 and gelatin in co-templating method via hydrothermal and pyrolysis treatments. The presence of gelatin increased the mechanical strength of Pluronic F127 which can sustain the uniform microspherical structure of carbon following pyrolysis at 950 °C. The diameter of MCMs were controlled by variation of weight ratios between Pluronic F127 to gelatin from 1:0.01 to 1:1. MCMs exhibited inter-particulate mesoporous structure with high thermal stability (<500 °C). The MCMs were used as adsorbent for removal of ibuprofen and the kinetic studies using linear regression analysis revealed the adsorption fits pseudo second-order kinetic. The rate of adsorption and the amount of adsorbed ibuprofen were correlated well with the surface area and the crystallite size of MCMs. The efficiencies of ibuprofen adsorption on MCMs were also investigated when ibuprofen was dissolved at different concentration of water and hexane mixtures, the effect temperature variation and the amount MCMs to the volume of ibuprofen solution.
采用 Pluronic F127 和明胶共模板法，通过水热和热解处理，得到了可调节尺寸的介孔碳微球（MCMs）。明胶的存在增加了 Pluronic F127 的机械强度，使其能够在 950°C 的热解过程中保持碳的均匀微球形结构。MCMs 的直径通过 Pluronic F127 与明胶的重量比从 1:0.01 至 1:1 的变化来控制。MCMs 具有介孔结构，具有高热稳定性（<500°C）。MCMs 用作布洛芬的吸附剂，通过线性回归分析的动力学研究表明吸附符合伪二级动力学。吸附速率和吸附的布洛芬量与 MCMs 的比表面积和晶粒尺寸密切相关。还研究了在不同浓度的水和己烷混合物中布洛芬溶解时，温度变化和 MCMs 对布洛芬溶液体积的影响对 MCMs 吸附布洛芬的效率的影响。
