Sorption studies of 4-NP onto goethite: effects of contact time, pH, concentration, ionic strength and temperature

Facile synthesis of C30-AuNPs for the effective catalytic reduction of nitrophenols and azo dyes

“…The US Environmental Protection Agency has reported that 4-NP is carcinogenic, hepatotoxic and mutagenic, posing a significant risk to human life and health, and it has been placed on the US EPA's Priority Pollution List. [6][7][8][9][10] In recent years, electrochemical treatment, 11 photocatalytic degradation, 12 microbial degradation, 13 microwave catalytic oxidation, 14 electrocoagulation and adsorption 15 have been used to resolve the hazards of 4-NP pollutants. However, it has been found that the conversion of 4-NP by these methods is low and costly, and therefore, the green and simple reduction of 4-NP has received extensive attention.…”

Enhanced Adsorption Efficiency through Biochar Modification: A Comprehensive Review

“…The adsorption process is widely being used in water and wastewater treatment, air purification, environmental remediation, refinery operations, etc. An important application of adsorption is water purification, which involves the use of natural materials, industrial byproducts, and agricultural residues as adsorbents. , The simplicity, cost-effectiveness, and nontoxic nature of the adsorption process are the key driving factors behind its notable prominence and widespread adoption . The noticeable emphasis on using this process for wastewater treatment and water purification is attributed to its proven efficacy in decontamination.…”

Electrodialysis as a potential technology for 4-nitrophenol abatement from wastewater

“…The ED relevance in these applications is attributed to both its removal efficiency and its main operative advantages, including compact installations and short treatment times (Chang et al 2010;Lotfy et al 2022). Electrodialysis is a membrane technology considered advanced in environmental terms since it allows the removal of organic ions by one-step innocuous processes, carried out at room temperature and pressure and without the addition of harmful chemical compounds (Bernardes et al 2014;Rajoria et al 2022).…”
