BACKGROUND: The recovery and reuse of sonocatalysts are the pivotal issues in the sonocatalytic degradation of organic pollutants. The use of some natural minerals as the carrier is not only beneficial to recycling of sonocatalysts, but also reduces the treatment costs of organic pollutants. Two kinds of hydroxyapatite (HAP), Ox Bone (OB)-HAP and synthesized (Syn)-HAP combine with the Pt-TiO 2 /(Er 3+ :Y 3 Al 5 O 12 @Ta 2 O 5 ) (P-TET) composite, obtaining two Z-scheme sonocatalysts, P-TET/OB-HAP and P-TET/Syn-HAP, respectively. The sonocatalytic activities of the prepared samples are investigated via degradation of prometryn and disinfection of Escherichia coli.RESULTS: A series of characterizations showed that the Z-scheme P-TET/(OB or Syn)-HAP sonocatalysts were prepared successfully. To evaluate their sonocatalytic activities, some influencing factors such as ultrasonic irradiation time, inorganic oxidants, used times and trapping agents on the sonocatalytic degradation prometryn were determined. The best degradation ratio (80.31% based on N computing and 85.07% based on S atom computing) of prometryn could be obtained for 10 mmol L −1 K 2 S 2 O 8 , 1.0 g L −1 P-TET/OB-HAP sonocatalyst and 150 min ultrasonic irradiation. The excellent sonocatalytic disinfection ratio (88.65%) of E. coli could also be obtained under 40 min ultrasound irradiation. Moreover, a possible mechanism on sonocatalytic degradation of prometryn was illustrated.CONCLUSION: The treated bovine bone HAP was directly used as a carrier to combine with P-TET to construct a novel Z-scheme P-TET/OB-HAP sonocatalyst. The high degradation ratio of prometryn and disinfection ratio of E. coli showed that P-TET/OB-HAP could be a promising sonocatalyst for the degradation of organic pollutants and the disinfection of bacteria.

“…33 The band at 204 cm À1 is due to (O-Bi-O) symmetric bending mode. 34 Obviously, calcination of HBIP indicated a signicant changes in the Raman spectra. Under calcination of HBIP at 400 C, the n 3 asymmetric stretching band showed a blue shi to 1042 cm À1 , and slightly increased to 1037 cm À1 with increasing the calcination to 500 and 600 C. In addition at 500 C calcination temperature, the stretching mode of Bi-O located at 168 and 240 cm À1 are attributed to monoclinic Bi-O polyhedra.…”

BiPO4:Tb 3+ /Ce 3+ nanofibers are synthesized by a simple electrospinning process and followed by a calcination treatment. The nanofibers are characterized by TG-DSC, XRD, FT-IR, SEM, TEM, and spectrophotometer. The calicined BiPO4:Tb 3+ /Ce 3+ nanofibers have a monoclinic phase and the diameters are in the range of 80-200 nm. The SEM and TEM images show that the nanofibers are mesoporous and composed of lots of linked nanoparticles. Under an excitation at 369 nm, BiPO4:Tb 3+ and BiPO4:Tb 3+ /Ce 3+ nanofibers show characteristic emission bands originating from the 5 D4 → 7 Fj (j=6, 5, 4, and 3) transitions of Tb 3+ ions. The luminescent properties of BiPO4:Tb 3+ indicate that the quenching concentration for Tb 3+ ions in BiPO4 host is about 15mol%. The co-doped Ce 3+ ions can improve the emission intensity through the energy transfer from Ce 3+ to Tb 3+ ions.
