Opis:: Adsorption of methyl tert-butyl ether (MTBE) from aqueous solutions by granulated modifi ed nanozeolites Y was investigated. Nanozeolite Y powders were converted into granulated zeolites and subsequently modifi ed with two cationic surfactants (20 mmol/dm3), to be used as adsorbent. Granulated nanozeolites were characterized by BET surface area analysis, elemental analysis and X-ray diffractometer. Hexadecyltrimethylammonium (HDTMA-Cl) modifi ed granulated zeolite had more effective performance than N-cetylpyridinium bromide (CPB) modifi ed granulated zeolite. The most conventional adsorption isotherms and kinetic models were applied to describe MTBE adsorption and reaction dynamic, respectively. The equilibrium sorption data fi tted the Langmuir 2 isotherm model and the kinetic study was followed the pseudo-second-order model. The maximum adsorption capacities for HDTMA-Cl modifi ed zeolite and CPB modifi ed granulated zeolite were 333.33 and 142.8 mg/g, respectively as calculated by the Langmuir model. This study demonstrated that the removal of mtbe by granulated modifi ed nanozeolites Y is a promising technique.

Opis:: The temperature dependent biology of greenbug, Schizaphis graminum Rondani on Kavir barley cultivar was studied at seven constant temperatures including 10, 15, 19, 22, 26, 31, and 33±1°C, 70% relative humidity (RH), and a photoperiod of 16:8 (L:D) hours. The period of immature development ranged between 6.60 days at 26°C to 28.56 days at 10°C, respectively. All tested aphids failed to develop at 33°C. The calculated rm and λ values were significantly the highest at 26°C and lowest at 10°C, respectively. The mean generation time and doubling time of S. graminum decreased linearly by increasing the temperature from 10 to 26°C. Additionally, the total number of offsprings per female was extremely low at 10 and 31°C, contrary to the highest and lowest values of life expectancy at 10°C (41.73 days) and 31°C (7.66 days), respectively. The results of the present study revealed that temperature had great effects on biology of S. graminum, which was never previously studied on barley in Iran.
