What are the leading arsenic sorbing media and how are they made.
Focus specifically on the metal oxide filter media - e.g. Al and Fe
oxides. What I want is a manufacturers "How-to" description.

Request for Question Clarification by welte-ga on 23 Aug 2005 14:35 PDT

Hi travi4-ga,  I have tracked down several patents which describe the
manufacturing processes for the most popular arsenic adsorbing media,
as well as some more recent developments (e.g. Titanium compounds). 
There seems to be very little other information available regarding
the details of current manufacturing techniques for the various media.

Would such a list with summaries (with links to the actual patents)
suffice as an answer?
