Interactions of ammonium-smectite with volatile organic compounds from leachates

Volatile organic compounds from leaves litter.

Qualitative composition of volatile emissions of litter of five species of deciduous trees was investigated by GC-MS. The list of identified substances contains more than 70 organic compounds of various classes. It was established that the composition of components emitted by the litter into the gas phase greatly differs from that of essential oils extracted by hydrodistillation from turned lea...

Measurement of Volatile Organic Compounds

To answer critical questions regarding the interactions between green plants and air quality, two three-year projects are underway to investigate emission of volatile organic compounds (VOC) from selected plant species. These biogenic VOC (BVOC) and oxides of nitrogen (NOx) can react in the lower atmosphere in the presence of sunlight to form ozone and secondary particulate matter, the principa...

Catalytic Oxidation of Volatile Organic Compounds and Malodorous Organic Compounds

This thesis describes efforts made on the development of an existing catalytic incinerator. The development work, called process characterization, consists of four general parts. These are the development of measurement methodology, the studying of construction materials, the selection of suitable catalysts and the testing of the effects of process operation conditions. The two application area...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Volatile Organic Compounds in Uremia

BACKGROUND Although "uremic fetor" has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia. METHODS Breath analysis was performed in 28 adults with an eGFR ≥ 60 ml/min...
