<P style="TEXT-INDENT: 0cm; MARGIN-LEFT: 36pt"><SPAN lang=EN-US>Over the past 25
years, intensifying research into metal biosorption ellucidated the principles
of this effective metal-concentration phenomenon.<SPAN> </SPAN>Biosorption
can be very cost-effective particularly in environmental applications where a
low cost of the metal removal process is most desirable.<SPAN> </SPAN>Some
very efficient natural biosorbents have been identified, and more are
continuously reported upon, that require very little modification in their
preparation.<SPAN> </SPAN>The pretreatment needs will also be discussed in
this presentation.<SPAN> </SPAN>Engineering scale-up of the biosorption
process seems fairly straightforward, based on experience from conventional
sorption operations.</SPAN></P>
<P style="TEXT-INDENT: 0cm; MARGIN-LEFT: 36pt"><SPAN lang=EN-US>Perhaps it is
the interdisciplinary nature of biosorption investigations may be at the root of
many misconceptions in their conduct and result reporting.<SPAN>
</SPAN>The fundamentals of single- and multimetal equilibrium as well as dynamic
flow-through sorption column studies are summarized in this presentation that
also points out the main scientific pitfalls.</SPAN></P>
