The X-ray diffractograms (XRD) for the whole rock Bida shale samples from location A revealed minerals such as kaolinite, quartz, mordenite, microcline, zircon and gamma alumina (Figure 4a); kaolinite was the dominant clay mineral.
The Sandia researchers took the best elements of the zeolite Mordenite -- its pores, high surface area, stability and chemical absorption -- and identified a MOF that can separate one molecule, in this case iodine, from a stream of molecules.
There are nearly 50 different types of natural zeolites (CLP, mordenite, etc.
The most common minerals present in the deposits are mordenite, clinoptilolite, laumonite, and wairakite.

For example, after the Chernobyl nuclear accident, the mineral mordenite was added to animal feed in Sweden to remove cesium-137 from the gastrointestinal tracts of contaminated animals.
Geological Survey has reported natural zeolites' worldwide occurrence in the USA, Japan, Korea, Bulgaria, Czechoslovakia, Romania, Hungary, Russia, Yugoslavia, South Africa, Italy, Germany, Turkey and China, the latter having the greatest worldwide production Clinoptilolite, mordenite, heulandite, chabazite, phillipsite and laumontite are some of the more than 40 known natural zeolites occurring in reasonably high quantities and purity.
1993) studied the effects of various process parameters in isopropylation of benzene on beta and the performance of the catalyst has been compared with other catalysts like ZSM-12 and Mordenite.
In another study, we found that the mutagenic potential of mordenite was not enhanced by the addition of ferrous ion.
