Ozonation as an Advanced Treatment Technique for the Degradation of Personal Care Products in Water

Abstract

Water is the most essential element to life on Earth. However, the availability and quality of the global water resources are at risk because many stressors of human origin are putting pressure on it. The contamination of water bodies (lakes, rivers, aquifers and oceans) occurs when man-made chemicals are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds, affecting organisms living in these aquatic ecosystems. As new compounds are produced and ultimately detected in the environment, improved water treatment techniques have to be available for their elimination. For the degradation of a wide range of emerging organic micropollutants, last year's

The structure optimization of gas-phase surface discharge and its application for dye degradation

“…Some parts of the specific products are shown in table 1 [21][22][23]. Polyhydroxy compounds, aliphatics, unstable cyclic ozonide, carbonyl compound and carbonyl oxide molecules were formed through hydroxylation [24], demethylation [25] and ozonization [26], and finally they could result in CO 2 , H 2 O, -NO 3 and -SO 4 2 [27]. The degraded dye made biodegradation and subsequent processes much easier.…”

Kinetics and Mechanism of Oxidation of Carbenicillin by Copper (III) Periodate Complex in Aqueous Alkaline Medium

“…ese effects enhance bacterial or viral resistance [12,13] against different PADs, and hence, it is a great challenge before researchers and drug manufacturers [14] to modify their composition along with updated specific function with a view to get fast relief from the illness. Personal care products (PCPs) [15][16][17] and antibiotic resistance represent a serious health problem, and different advanced oxidation processes (AOPs) have to be applied to degrade such emergent chemical pollutants [18][19][20] because most of the intermediates, formed transiently, can be definitely mineralized into CO 2 , water, and mineral species due to possible oxidation-degradation reactions. e proposed work will disclose a novel application in the field of pharmaceuticals as well as kinetics for degradation of drugs and will be adequately applied in wastewater treatment at the sites polluted by PADs antibacterial agents.…”
