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 H2O2 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.
