[en] The present work aimed to study the processes of the synthesis insecticidal formulation. The active compounds of essential oil of eucalyptus globulus were fixed in the palygorskite by adsorption process. Two samples types of palygorskites were used; raw and modified palygorskite. The palygorskite clays were characterized by several physicochemical techniques including X-Ray Diffraction (XRD) and Fourier Transformed Infra Red (FTIR) analyses. Results show that the raw clay has a fibrous structure with calcite impurities. These structures and physicochemical properties of palygorskite raw and organo-clays 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 clays. The highest adsorption capacity of terpenic compounds is obtained with palygorskite modified by DDDMA. These results revealed the potential utility of the S1-DDDMA as adsorbents for the uptake of terpenic compounds in environmental applications.
