A comparative study of electrochemical degradation of benzoic acid and terephthalic acid from aqueous solution of purified terephthalic acid (PTA) wastewater

Sandhwar, Vishal Kumar; Prasad, Basheshwar (Journal of Water Process Engineering | Volume 30, 2019-08)

In this article, studies have been performed on the treatment of benzoic acid (BA), terephthalic acid (TPA) and COD from synthetic binary solution of PTA wastewater. Acid precipitation pretreatment of aqueous solution was ...
Comparative study of electrochemical oxidation and electrochemical Fenton processes for simultaneous degradation of phthalic and para-toluic acids from aqueous medium

Sandhwar, Vishal Kumar; Prasad, Basheshwar (Journal of Molecular Liquids | Volume 243, 2017-10)

Degradation of binary component of purified terephthalic acid wastewater viz. phthalic acid and para-toluic acid from aqueous medium was investigated in this study. Aqueous solution was initially subjected to acid precipitation ...
Comparative study of electrocoagulation and electrochemical Fenton treatment of aqueous solution of benzoic acid (BA): Optimization of process and sludge analysis

Sandhwar, Vishal Kumar; Prasad, Basheshwer (Korean Journal of Chemical Engineering | Volume 34 | Issue 4, 2017-04)

Benzoic acid containing synthetic solution was pretreated by acid precipitation at various pH (1-3) and temperature (15-60 °C). Pre-treated solution was further treated by electrocoagulation (EC) and electrochemical Fenton ...
Comparison of COD removal from petrochemical wastewater by electro-Fenton and electro oxidation processes: optimization and kinetic analyses

Sandhwar, Vishal Kumar; Saxena, Diksha; Verma, Shilpi; Garg, Krishan Kishor; Prasad, Basheshwar (Separation Science and Technology | Volume- | Issue-, 2020)

This study reveals comparison between electro-Fenton (EF) and electro-oxidation (EO) methods to study chemical oxidation demand (COD) removal from synthetic petrochemical wastewater. Initially 54.60% of COD removal was ...
Comparison of phthalic acid removal from aqueous solution by electrochemical methods: Optimization, kinetic and sludge study

Sandhwar, Vishal Kumar; Prasad, Basheshwar (Journal of Environmental Management | Volume 203 | Issue 1, 2017-12)

In this work, comparative study between electrochemical processes such as electrocoagulation (EC), peroxi-coagulation (PC) and peroxi-electrocoagulation (PEC) was performed for the removal of phthalic acid (PA) and chemical ...
Terephthalic acid removal from aqueous solution by electrocoagulation and electro-Fenton methods: Process optimization through response surface methodology

Sandhwar, Vishal Kumar; Prasad, Basheshwar (Process Safety and Environmental Protection | Volume 107, 2017-04)

The present work deals with the treatment of terephthalic acid (TPA) and chemical oxygen demand (COD) from synthetic aqueous solution. Initially the aqueous solution was treated by acid precipitation at different pH (2–5) ...
