Effect of intensifying additives on the degradation of thiamethoxam using ultrasound cavitation

Ultrasonics Sonochemistry, 2021
The present study has investigated the degradation of thiamethoxam using ultrasound cavitation (US) operated at a frequency of 20 kHz and its combination with intensifying additives viz. hydrogen peroxide, Fenton and photo-Fenton reagent.

An enhanced treatment efficiency for diluted palm oil mill effluent using a photo-electro-fenton hybrid system [PDF]

Journal of the Serbian Chemical Society, 2019
Photocatalysis, electrolysis and Fenton process are three important advanced oxidation processes (AOPs) which produce hydroxyl radical in order to degrade organic matter in wastewater within 4-6 hours under ambient conditions.

Photo oxidative degradation of azure-B by sono-photo-Fenton and photo-Fenton reagents

Arabian Journal of Chemistry, 2014
AbstractA model for the decomposition of azure-B by photo-Fenton reagent in the presence of ultrasound in homogeneous aqueous solution has been described. The photochemical decomposition rate of azure-B is markedly increased in the presence of ultrasound. It is a rather inexpensive reagent for wastewater treatment.

Ferroin in dyes degradation by Fenton-like process: a chemical waste recycling perspective

Water Science and Technology, 2021
Published literature describes the formation of the Fe (II)–phenanthroline complex (ferroin) as a stop way for Fenton processes, reducing radical yield. By contrast, this study presents evidence that ferroin can be activated by UVA in mildly acidic media
