[APD] adsorption of phosphate ions by diatomaceous earth or other materials

["Steve Pushak" <teban at powersonic_bc.ca>]

Can anyone with a technical background comment on the following as it
relates to phosphate adsorption by diatomaceous earth?

<http://www.scipress.com/adsorption,_ion_metal,_diatomaceous_earth.htm>

I suspect that there a number of materials that are capable of adsorbing
ions aside from activated carbon. Zeolite + Acinetobacter calcoaceticus
is another promising phosphate remover.

See <http://public.srce.hr/ftbrfd/41-331.pdf>

I believe I previously mentioned zeolite for sequestering ammonia in the
substrate. Any comments on zeolite?
