Abstract

STUDY OF THE PROPERTIES AND MORPHOLOGICAL STRUCTURE OF NATURAL ZEOLITE PREPARED FROM LOCAL CLAY RAW

Firas Emad Fatthee* and Omar Musa Ramadhan

ABSTRACT

This study included the use of local clay raw, which is found in large quantities in the Al-Qasr area of Nineveh Governorate, Iraq. The study showed that it contains many important clay minerals its rich in clay minerals, which are Montmorillonite (10%), chlorite (4%), Kaolinite (9%), muscovite (20%) and illite (19%) which represent more than two thirds of the clay raw, in addition to containing small quantities with different percentages of non-clay minerals. Chemical treatments have also proven their ability to remove impurities from clay raw, which reduces its effectiveness, in addition to its ability to open pores and channels, and this has been proven in BET and SEM analyzes. Natural zeolite prepared from clay raw, many measurements were made (TG, DTA, XRD, XRF, BET, SEM) which proved that natural zeolite was obtained with good qualities, as it can be used as an ion exchanger or in the various catalytic processes.
