Published: Dec. 27, 2019

In this work, the application of advanced oxidation processes (AOPs) for removal antibiotics from water has been reviewed. The present concern about exposed, and main problems derived presence emerging pollutants have analyzed. Photolysis processes, ozone-based AOPs including ozonation, O3/UV, O3/H2O2, O3/H2O2/UV, hydrogen peroxide-based methods (i.e., H2O2/UV, Fenton, Fenton-like, hetero-Fenton, photo-Fenton), heterogeneous photocatalysis (TiO2/UV TiO2/H2O2/UV systems), sonochemical electrooxidative challenges prospects AOPs, as well some recommendations improvement aimed at wastewaters, are pointed out.

Present and past anthropogenic pollution of the hydrosphere lithosphere is a growing concern around world for sustainable development human health. Current industrial activity, abandoned contaminated plants mining sites, even everyday life source our environment. There therefore crucial need to clean municipal effluents remediate soil groundwater. Nanosized zero-valent iron (nZVI) an emerging material in these fields due its high reactivity expected low impact on environment iron’s abundance earth crust. Currently, there intensive research test effectiveness nZVI contaminant removal processes from water modify properties this order fulfill specific application requirements. The number laboratory tests, field applications, investigations environmental are strongly increasing. aim present review provide overview current knowledge about catalytic efficiency removing toxic organic inorganic materials water, wastewater, groundwater, as well effect microorganisms plants.

Catalytic activity of metals in heterogeneous Fenton-like oxidation of wastewater contaminants: a review

Environmental Chemistry Letters, Journal Year: 2021, Volume and Issue: 19(3), P. 2405 - 2424

Published: Feb. 14, 2021

Abstract Innovations in water technology are needed to solve challenges of climate change, resource shortages, emerging contaminants, urbanization, sustainable development and demographic changes. In particular, conventional techniques wastewater treatment limited by the presence poorly biodegradable organic matter. Alternatively, recent Fenton, Fenton-like hybrid processes appear successful for cleaning different types liquid wastewaters. Here, we review application metallic catalyst-H 2 O systems heterogeneous Fenton process. Each system has unique redox properties due metal oxidation state. Solution pH is a major influencing factor. Catalysts made iron cerium form stable complexes with products H , thus resulting reduced activities. Copper forms transitory products, but copper catalytic activity restored during reaction. Silver manganese do not complexes. The catalyst performance degradation mineralization decreases order: manganese, copper, iron, silver, cerium, yet easiness practical cerium.

Emerging pollutants of severe environmental concern in water and wastewater: A comprehensive review on current developments and future research

Water-Energy Nexus, Journal Year: 2023, Volume and Issue: 6, P. 74 - 95

Published: Aug. 30, 2023

Environmental contaminants have emerged significantly due to the enormous consumption of medications, personal-care products, antibiotics, and hormones for cosmetic health reasons. Emerging pollutants (EPs), often alluded as contaminants, become a massive concern entire populace their immense critical environmental human hazards. EPs broad range effects. emanate from either or animal origins, with ability permeate streams instantaneously gradually through soils. Consequently, potable water sources will get tainted, quality degrade, conditions emerge. For more than decade, research has been conducted on various pollutants, but this developing class mainly comprises those fertilizer, pharmaceutical, personal care industries. Even in lower quantities, majority evolving may be harmful people marine life. These chemicals lack defined limits because treatment facilities require sources. The prevalence deterioration aquatic environments, particularly surface groundwater, is severe problem. technologies utilize methodologies, including physicochemical, biological, modern oxidation processes, regardless benefits limitations.

Nanocatalyst‐Mediated Chemodynamic Tumor Therapy

Advanced Healthcare Materials, Journal Year: 2021, Volume and Issue: 11(2)

Published: Nov. 9, 2021

Abstract Traditional tumor treatments, including chemotherapy, radiotherapy, photodynamic therapy, and photothermal are developed used to treat different types of cancer. Recently, chemodynamic therapy (CDT) has been emerged as a novel cancer therapeutic strategy. CDT utilizes Fenton or Fenton‐like reaction generate highly cytotoxic hydroxyl radicals (•OH) from endogenous hydrogen peroxide (H 2 O ) kill cells, which displays promising potentials for treatment. However, the low catalytic efficiency off‐target side effects limit biomedical application CDT. In this regard, various strategies implemented potentiate against tumor, retrofitting microenvironment (e.g., increasing H level, decreasing reductive substances, reducing pH), enhancing nanocatalysts, other strategies. This review aims summarize development these recent progresses nanocatalyst‐mediated antitumor application. The future trend challenges also discussed.
