The EPNs were tested in baits containing cat food and
attapulgite clay because such baits would be relatively inexpensive to produce and easy to use.
A fortnight later, the 80 most vigorous plantlets were transplanted singly to 1-L pots (14 x 10 cm), filled with pasteurized field soil [clay loam, pH ([H.sub.2]O) = 5.8; available P (Olson) = 52 mg P [kg.sup.-1]] silica sand (0.7-1.2 mm) and expanded,
attapulgite clay (Oil Dry Chem-Sorb WR 24/18, Brenntag Mediterranee Export, Vitrolles Cedex, France), mixed in a volumetric ratio of 1:2:2.
Nanoporous zeolites,
attapulgite clays (which can bind large numbers of bacteria and toxins), and nanoporous polymers (which can bind 100,000 times more organic contaminants than can activated carbon) can all be used for water purification.

Zemex Corporation acquired
attapulgite clay assets from Milwhite
Materials evaluated were SW-101, Hydrogel 90 (API material) Extra High Yield and
Attapulgite, in varying concentrations mixed into sea water.
It has been demonstrated in recent studies that high-surfacearea clays such as smectic and
attapulgite are effective in inducing these cytoprotective effects and alleviating the symptoms of diarrhoea (Gilardi et al 1999:917).
Update: Added a line of organoclays, dropped a line of
attapulgite clays
Salt Gel: An

Palygorskite, also known as,
attapulgite, is a clay mineral mined from Miocene strata north of Tallahassee, Florida.
