Photochemical oxidation of aromatic hydrocarbons leads to tropospheric ozone and secondary organic aerosol (SOA) formation, with profound implications for air quality, human health, and climate. Toluene is the most abundant aromatic compound under urban environments, but its detailed chemical oxidation mechanism remains uncertain. From combined laboratory experiments and quantum chemical calcul...
Effects of p-cresol on photosynthetic and respiration rates of a filamentous green alga (Spirogyra).
Development of coal gasification plants in the United States for the generation of electrical power (SPENCER et al. 1982) may increase the probability of accidental spills of coal-derived phenols and monohydric cresol isomers into streams and rivers. Although Europe has experienced several accidental spills from coal fired electrical plants and phenol producing plants (ALABASTER et al. 1973), m...
This study investigated the catabolic potential of a eukaryotic alga to degrade one of the most common organic pollutants, phenol. The alga, Ochromonas danica (993/28), was selected for study after screening for its heterotrophic capabilities. The catabolic versatility of the alga was elucidated by incubating with a variety of phenolic compounds. The alga removed phenol, all the cresol isomers ...
Vanadium substituted mesoporous AlPO have been synthesised using structure-directing surfactant under hydrothermal synthesis conditions. The presence of V in the framework of AlPO has been established by ESR, XPS, UV–vis DRS and ICP-AES measurements. This system is capable of promoting the oxidation of toluene to aldehyde and benzoic acid when the oxidising agent is 70% tert-butyl hydroperoxide...
