AI Article Synopsis
- Ultrasound was used to synthesize SnS and SnS powders, utilizing indirect sonication at 40 kHz and 38 W/L, and various characterization techniques were employed to assess the products.
- The synthesized microparticles were applied as a tip coating on copper cathodes, which were then tested for their effectiveness in degrading the azo dye Metanil Yellow using the electro-Fenton process.
- The study revealed that degradation kinetics followed a pseudo-first-order rate, where SnS-coated copper cathodes enhanced degradation efficiency, while copper cathodes without the coating showed decreased effectiveness.
Article Abstract
SnS and SnS powders were synthesized with the use of ultrasound. The indirect sonication was applied with ultrasound frequency 40 kHz and acoustic power 38 W/L. Products of syntheses were examined with PXRD, TEM, EDX, XPS, and UV-Vis (the Tauc method) investigations. The resulting microparticles were used for tip coating of copper cathodes. These electrodes were used in the degradation of model azo-dye Metanil Yellow by the electro-Fenton process. The efficiencies of degradation using copper, SnS-coated copper, and SnS-coated copper cathodes are compared. Kinetics of degradation of Metanil Yellow in the electro-Fenton process with the application of three different cathodes is also investigated. It was found that the degradation follows pseudo-first-order and that SnS-coated copper cathode improves the efficiency of degradation, while SnS-coated copper cathode decreases the efficiency of degradation.
