A NaP zeolite doped with titanium (Ti-NaP) was prepared by a hydrothermal method and a complexation method using sodium silicate and sodium meta-aluminate from coal fly ash by grading extraction as raw materials based on a scientific concept of "sewage purification by solid waste". The crystal phase, morphology, and existed state of elements in NaP zeolites before and after doping titanium were characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and solid magic angle spinning nuclear magnetic resonance of silicon and aluminum. The adsorption performance of Ti-NaP was also evaluated. The experimental results show that when n(Al2O3)∶n(TBOT)=6∶1, the crystallinity of Ti-NaP reaches 98.2%, and the existed state of titanium in NaP zeolite mainly includes the isomorphous substitution with silicon atom in the skeleton and the balance of skeletal negative charge. The specific surface area of Ti-NaP is 123 m2/g, which is approximately 3.6 times greater than that of NaP zeolite un-doped with titanium (27 m2/g). The test results of Zn(II) adsorption show that the removal rate of Zn(II) of Ti-NaP is 97.71%. Moreover, Ti-NaP still remains a good adsorption stability after 5 cycles of adsorption-regeneration.
