zeolites are wide used as additives in feed. But not nanozeolites. I do not know neither if such is a product of processing naural zeolites or it is artificially obtained
Thank you
Thank you very much for your respons.
By the way, Do you know something about organozeolites. I meen zeolites modified with cationic surfactants as mycotoxin sequestrants for feed?. Will they be also regulated?
Zeolites due to the nanopores are highlighted as nanotech category. Making them as nano may additionally help to get more external surface area in addition to the internal surface area. This is an interesting area. A review can be found on Nanozeolites: Synthesis, Crystallization Mechanism, and Applications at

Regarding the organo-zeolites, Peter lego from UK has done some work in that direction.The followimh is the citation of the article.

It may throw more light on this aspect. In india we are trying for organo-zeolites for enhanicng the use efficiency of organic manures. A report was presented at ASA symposium during 2012.
I have reproduced the abstract below.
Zeolites Regulate Nitrogen Release From Manure-Amended Soil.

Manure-zeolite amendment of soil has recently been evolved as a novel approach to minimize reactive nitrogen formation and loss from agricultural fields. Zeolites are nanoporous secondary minerals having a high selectivity for cations especially ammonium ion which could be used for slow release of nutrients through organo-zeolite mixture concept. To study the effects of zeolite on regulating nitrogen release, a lab incubation study using dairy manure mixed with naturally mined zeolite (such as Clinoptilolite) was conducted at the Ohio State University South Centers at Piketon, USA during August and September of 2011. Zeolite and manure treatments were: Manure at 50-g oven-dried equivalent (M50); Zeolite + Manure at 1:5 ratio (ZM1:5), ZM1:10, ZM1:15, ZM1:20 and ZM1:30, respectively mixed with soil and replicated 6 times. The zeolite-manure amended soil in different treatment combinations were incubated at room temperature (~25 0C) for 7 days. The replicated samples of zeolite-manure treatments were taken every day over a period of 7 days and ammonium and nitrate concentration was measured calorimetrically. Results showed that the ZM1:15 had steadily and consistently release ammonium with a non-linear (parabolic) dynamics over time.
We may have collaborative work if possible.
