Hierarchical porous m.gnesium.silicate hydrate (m.H) m.crospheres com.osed of sheets are successfully developed under facile conditions using a hard tem.late. The role of hexadecyltrim.thylam.onium.brom.de (CTAB) on the form.tion and adsorption behavior was also observed for the m.thyl orange and m.thylene blue. The form.d m.H possesses a surface area of 453.24 m.(2)/g, an average pore size of 6.38 nm. and a pore volum. of 0.75 cm.(3)/g without CTAB. Based on the role of CTAB and the change in the ratio of m./Si, the m.H retained its sphere-like structure with a variation in pore param.ters. The form.d m.H was used as an adsorbent to rem.ve m.thylene blue and m.thyl orange. The pseudo-second-order kinetic and Langm.ir Isotherm.m.dels are well-fitted, with a 256.4 m./g rem.val capacity and 84.2 m./g for m.thylene blue and m.thyl orange, respectively. The m.dified m.H with CTAB played a positive role for the m.thyl orange and a negative role for the m.thylene blue regarding rem.val perform.nce.
