Nanofiltration and nanostructured membranes—Should they be considered nanotechnology or not?
Journal of Hazardous Materials, 2012, 211-212, 275-280
Abstract:
Nanofiltration is frequently associated with nanotechnology – obviously because of its name. However,
the term “nano” in nanofiltration refers – according to the definition of the International Union of Pure
and Applied Chemistry (IUPAC) – to the size of the particles rejected and not to a nanostructure as defined
by the International Organisation of Standardisation (ISO) in the membrane. Evidently, the approach to
standardisation of materials differs significantly between membrane technology and nanotechnology
which leads to considerable confusion and inconsistent use of the terminology. There are membranes
that can be unambiguously attributed to both membrane technology and nanotechnology such as those
that are functionalized with nanoparticles, while the classification of hitherto considered to be conventional
membranes as nanostructured material is questionable. A driving force behind the efforts to define
nanomaterials is not least the urgent need for the regulation of the use of nanomaterials. Since risk estimation
is the basis for nanotechnology legislation, the risk associated with nanomaterials should also
be reflected in the underlying standards and definitions. This paper discusses the impacts of the recent
attempts to define nanomaterials on membrane terminology in the light of risk estimations and the need
for regulation.
