摘要: Abstract This paper describes a simple and effective process for fabricating porous P-type zeolite spheres from metakaolin-based geopolymers. The are first synthesized by suspension solidification method that is based on the rapid mechanism of geopolymer slurries in high-temperature suspensions. then transformed into an situ hydrothermal at 140 °C 10 h. X-ray diffraction (XRD) scanning electron microscopy (SEM) analyses indicated constructed zeolites. Analysis pore structure revealed BET surface area 4.21 m 2 /g 42.08 m /g, respectively. increased attributed to use sodium dodecyl sulfate (K 12 ). work provides possible way continuous-mode water treatment.
