Carrageenan as an abundant natural carbohydrate could be used as a representative material instead of synthetic polymers. In this work, the degradation of κ-Carrageenan by means of ultrasound irradiation at a frequency of 24 kHz and its combination with heterogeneous Titanium dioxide, followed by a photocatalytic process was investigated. The scission of carrageenan chains induced by a high int...

Sono, photo and sonophotocatalysis are major Advanced Oxidation Processes (AOP) under intensive investigation as potential technologies for the removal of trace pollutants from water.The techniques involve the formation and participation of Reactive Oxygen Species (ROS) like . OH, HO2 . , O2 . , H2O2 etc. Among these, H2O2 is the most stable and is also a precursor for the reactive free radical...

Here, the magnetic Fe3O4@SiO2/PAEDTC@MIL-101 (Fe) with a new core-shell structure was synthesized, and its sonophotocatalytic properties were evaluated for acid red 14 (AR14) degradation. Particle characterizations determined by scanning electron microscope (SEM), transmission microscopy (TEM), X-ray powder diffraction (XRD), vibrating-sample magnetometer (VSM), analysis results offered an exce...

In this study, the ultrasonic, photocatalytic and sonophotocatalytic degradation of organics in textile industrial effluent was studied using ZnO nano catalyst, ZnO nano catalyst was synthesized by using sol-gel method. The structure and morphology of the catalyst were investigated using scanning election microscopy (SEM), electron dispersive X-ray spectroscopy (EDS) and X-ray <span id="transma...
