Depending on the operating conditions and the age of the converter, mean platinum emissions ranged from 7 to 123 ng m-3 corresponding to emission factors between 9 and 124 ng km-1. There were no statistically significant differences between the four

Automobile exhaust catalytic converters emit fine dispersed elemental platinum, Pt (0), in the nanometer range coated on larger aluminium oxide carrier particles. A pre-requisite for a potential systemic toxic effect of the emitted platinum is its bi

A model catalyst to simulate inorganic emissions from automotive catalyst was developed to study the toxicological potential of platinum particles. A 3–5% systemPt/Al2O3 was selected in order to achieve sufficient analytical sensitivity in later to

A method for the separation and determination of tetrachloroplatinate, PtCl42−, and hexachloroplatinate, PtCl62−, applying UV absorption detection was developed and statistically validated. Independent and specific Pt quantification was possible

Automobile catalytic converters emit nanocrystalline platinum attached to alumina particles. For investigations about the bioavailability of Pt from these particles a model substance with approx. 5% Pt on alumina has been prepared and characterized b

From many years of experience with stationary technical catalytic converters it is known that part of the active material becomes detached and is released. This depends upon pressure, temperature and other operating conditions. Thus, despite subseque

Nach der Einfuhrung des PGE-haltigen Katalysators zur Reduzierung der Schadstoffemissionen im Automobilabgas Anfang der 70iger Jahre in den USA wurde bald deutlich, das eine hohe Abrasionsrate des Katalysators zur Deposition der PGE in der naheren Um

Aus langjahrigen Erfahrungen mit stationaren technischen Katalysatoren ist bekannt, das in Abhangigkeit von Druck-, Temperatur- und anderer Betriebsbedingungen ein Teil des aktiven Materials losgelost und freigesetzt wird. So schatzte man etwa den Pl
