Background & Aims of the Study: Azo dyes are employed in industrial processes such as textile industry to create large quantities of colored sewages that have organic and non-organic materials. So, remediation of them is essential. In this project, degradation and mineralization of Acid red 14 (AR14) that is a mono Azo dye and widely used in the textile industries was investi...

In this work, a novel sol-gel-based procedure to obtain solid carbon composite electrodes is proposed. The procedure is based on the use of sonocatalysis to apply high-energy ultrasound directly to the precursors; this way, ultrasonic cavitation is achieved so that hydrolysis with acidic water is promoted in the absence of any additional solvent and the time needed to get a unique phase is redu...

Lignocellulosic biomass represents a natural renewable chemical feedstock that can be used to produce high value-added chemicals and platform molecules. Nowadays, there are extensive studies on a variety of aspects concerning the valorization of lignocellulosic biomass into desirable products. Among the current technologies for biomass conversion some require extreme conditions along with high ...

Landfills leachates are known to contain recalcitrant and/or non-biodegradable organic substances and biological processes are not efficient in these cases. A promising alternative to complete oxidation of biorecalcitrant leachate is the use of ultrasonic process as pre-treatment to convert initially biorecalcitrant compounds to more readily biodegradable intermediates. The objectives of this s...

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...

This work investigates the degradation of azo dye solochrome dark blue (SDB) by measurement photocatalytic, sonocatalytic and sonophotocatalytic activities, under low ultrasonic frequency (40 kHz) UV-C (254 nm) light, using Mn-doped ZnS semiconductor quantum dots (Mn2+:ZnS Qds) as catalysts, prepared a simple chemical precipitation procedure. In order to study different morphological optical cr...

1. Introduction One of the most important recent applications of sonochemistry has been to the synthesis and modification of inorganic materials [1-5]. In liquids irradiated with high intensity ultrasound, acoustic cavitation drives bubble collapse producing intense local heating, high pressures, and very short lifetimes; these transient, localized hot spots drive high energy chemical reactions...
