Degradation of pentachlorophenol aqueous solutions using a continuous flow ultrasonic reactor: experimental performance and modelling

ultrasonic degradation of hydrogels in aqueous solutions

continuous exposure to high-energy ultrasonic waves depolymerises macromolecules in solutions and produces a permanent reduction in viscosity. different factors affect the efficiency of this ultrasonic depolymerisation. in this work ultrasonic degradation of one commercially important hydrogel based on acrylic acid and acrylamide was carried out in aqueous solution at room temperature (25oc). a...

Methylene blue removal from aqueous solutions by electrocoagulation in continuous flow reactor: Modeling and optimization of operating parameters

Introduction The application and increasingly produce of colorants, particularly, synthetic dyes, are one of the main environmental and health concerns especially in industrialized countries. If this type of dyes is discharged into the environment without any control, many problems will arise. Therefore, it is necessary to remove the dyes from aqueous solutions using appropriate methods. The p...

Biosorption of Pentachlorophenol from Aqueous Solutions by Aspergillus Niger Biomass

Background: This study aimed to investigate the biosorption of pentachlorophenol on Aspergillus niger biomass as a method for removal of pentachlorophenol from aqueous solutions. Methods: Modified A. niger biomass with NaOH was used to absorb the pentachlorophenol. The impacts of various experimental parameters like primary pentachlorophenol concentration, pH of the solution, contact time, a...

Photocatalytic Degradation of Bisphenol A from Aqueous Solutions using TiO2 Nanoparticles and UV Illumination

Background and Purpose: Bisphenol A (BPA) is used to make certain plastics and epoxy resins. It is a non-biodegradable compound, and poses health risks to both humans and animals. The purpose of this study was to evaluate decomposition efficiency of BPA from aqueous solutions using UV irradiation. Materials and Methods: In this study, the photodegradation of BPA in water were carrie...
