Controllable Preparation of Zeolite-P/Calcined Diatomite with MgCl 2
Abstract
Developing highly effi cient calcined diatomite (C-D)-based fi lter aids with excellent adsorption performance is of great
signifi cance. Herein, Zeolite-P was successfully synthesized on the surface of C-D through hydrothermal modifi cation with
NaOH and MgCl 2 as effi cient morphology control agents. The optimal Zeolite-P/C-D material perfectly retained the diatomite
structure and showed a whiteness of 83.36% and a high specifi c surface area of 237.47 m 2 /g, leading to an excellent
adsorption capacity for methylene blue trihydrate (MB) of 125.46 mg/g and a good permeability of 0.43 darcy. The porous
fi brous microspheres Zeolite-P was synthesized on the surface of C-D under controlled conditions to improve the adsorption
performance of Zeolite-P/C-D material. By developing diatomite-based composites for fi lter aids applications, this study
paves the way for the comprehensive and effi cient utilization of low-cost diatomite resources.
