One of the most common environmentally relevant groups pollutants are phthalate esters. After decades industrial use, they have become ubiquitous in environment and analytical methods to chemically detect them trace amounts required. In this study, details Proton Transfer Reaction-Mass Spectrometry (PTR-MS) investigations for reactions phthalic acid ten esters with H3O+ as a function reduced el...

Laboratory smog chamber experiments have been carried out to investigate secondary organic aerosol (SOA) formation from the photooxidation of naphthalene and its methyl analogs, 1and 2-methylnaphthalene (1-MN and 2MN, respectively). Laboratory smog chamber irradiations were conducted in a flow mode to ensure adequate collection of the aerosol at reasonably low reactant concentrations and in the...

Plasticizers are additives that are used to increase the flexibility of plastic during manufacturing. However, in injection molding processes, plasticizers cannot be generated with monomers because they can peel off from the plastics into the surrounding environment, water, or food, or become attached to skin. Among the various plasticizers that are used, 1,2-benzenedicarboxylic acid (phthalic ...

Abstract Wastewater is major source of contaminants originating from the production, usage, and disposal plastic materials. Due to their poor biodegradability these in municipal wastewater treatment plants, additional advanced oxidation processes such as electrochemical treatments have been developed improve standard biological treatment. Here we review applications for removal following contam...
