ABSTRACT = {In this study, a magnetic P zeolite was directly synthesized by utilization of industrial solid wastes of zinc slag (ZS) and circulating fluidized bed fly
ash (CFBFA) via one-step hydrothermal method. The effects of different
CFBFA/ZS ratios and hydrothermal times on the as-synthesized zeolite were
investigated. The X-ray diffraction (XRD) and vibrating sample magnetometer
(VSM) results indicated that the magnetic P zeolite possessed well-defined
crystals and superparamagnetism. The as-prepared zeolite was employed as a
Fenton-like solid catalyst for degradation of direct green B dye wastewater. It
was discovered that the magnetic P zeolite took the advantage of rapid separation
and efficient recovery under the external magnets in a solid-liquid reaction. The
effects of the solution pH, the catalyst dosage, and the H<sub>2</sub>O<sub>2</sub> concentration on
the degradation rate of direct green B dye wastewater were studied systematically.
The results showed that the highest degradation of 96.3% was obtained and the
magnetic P zeolite showed excellent stability after four cycles. Therefore, the
magnetic P zeolite derived from industrial solid wastes had a potential application
in wastewater treatment.},
