Abstract :
[en] Essential oils of aromatic plants are currently mentioned as suitable tools for excellent protection of stored grains from insect pest attacks. The present work aimed to study the processes of the synthesis insecticidal formulation. The active terpenic compounds of essential oil of eucalyptus globulus were fixed in the palygorskite by adsorption process. Two samples types of palygorskites were used; raw and organo-palygorskite. The palygorskite clays were characterized by different physicochemical techniques including X-RAY Diffraction (XRD), Fourier Transformed Infra Red (FTIR) analyses, Thermogravimetric analysis (TG) and differential thermal analysis (DTA), (BET) and Scanning Electron Microscope (SEM). Results reveal that the raw clay has a fibrous structure with impurities essential calcite. These structures and physicochemical properties of raw palygorskite and organo-palygorskite give it the potential of material adsorbent. Results show that the adsorption capacity strongly depends on affinity between terpenic compounds and organic cations rather than on interlayer distance of organo-palygorskite. The highest adsorption capacity of terpenic compounds is acquired with palygorskite interlaced by DDDMA. These results validated the potential utility of the Paly-DDDMA as adsorbents fibrous clay for the retention of terpenic compounds in application of environmental preservation.
