Preface<br />
This project was <strong>in</strong>itiated by the Danish Environmental Protection Agency as<br />
part <strong>of</strong> the programme “Miljøeffektiv Teknologi – <strong>Substitution</strong> af<br />
problematiske kemikalier” (Environmentally effective technology –<br />
<strong>Substitution</strong> <strong>of</strong> problematic chemicals”.<br />
The project was carried out <strong>in</strong> the period August 2009 to February 2011.<br />
Sidsel Dyekjær and Mikkel Aaman Sørensen from the Danish EPA supervised<br />
the project.<br />
The purpose <strong>of</strong> this project was to f<strong>in</strong>d an alternative to <strong>PFOS</strong> <strong>use</strong> as a mist<br />
suppressant <strong>in</strong> non-decorative <strong>hard</strong> <strong>chrome</strong> plat<strong>in</strong>g, a <strong>PFOS</strong> <strong>use</strong> which<br />
presently is exempted from the EU ban <strong>of</strong> <strong>use</strong> <strong>of</strong> <strong>PFOS</strong>, beca<strong>use</strong> <strong>of</strong> lack <strong>of</strong><br />
alternatives.<br />
Various chemical and physical alternatives were tested <strong>in</strong> laboratory scale. A<br />
non-<strong>PFOS</strong> alternative as mist suppressant chemical was tested <strong>in</strong> a larger scale<br />
at a <strong>hard</strong> <strong>chrome</strong> plat<strong>in</strong>g company <strong>in</strong> Denmark.<br />
