A series of porous silica materials coated with honeycomb-like magnesium silicate were prepared under hydrothermal conditions, using natural one-dimensional attapulgite as the template and a silicon source different Mg/Si ratios, by adjusting amount MgCl2⋅6H2O precursor regulating pH. The influence ratios was carefully investigated on morphology, pore structure, related adsorption actions toward methylene blue. Langmuir isotherm pseudo-second-order kinetic models used to explain behavior synthesized composite lowest content displayed highest removal capability 166.67 mg/g for blue, zeta potential −18.18 mV, specific surface area 310.4 m2/g, an average size 3.7 nm. result synergetic between grown rest silica, further indicating that is available rod-shaped silicate.
