RISRemoval of anthropogenic lead pollutions by a potent Bacillus species AS2 isolated from geogenic contaminated site
A total of 422 bacterial isolates were obtained from the lead (Pb) ore in north-eastern Iran. The Pb tolerances of these strains were studied using microbroth serial dilution approach and 35 strains could grow up to 3250 ppm Pb concentration...
Role of Heavy Metal Ions in the Formation of Oxyfluoride Glasses and Glass Ceramics
Investigation of Effective Parameters on Adsorption of Pb2+ by Natural Goethite from Hurmoz Island, Persian Gulf
that has high
ability for adsorption of heavy metals. For this
purpose, adsorption ability of Pb2+was examined by
a sample of natural goethite from Hurmoz island ,
south of Iran and effective parameters on adsorption...
Structural, electronic and optical properties of lead zirconate
The structure, the band structure, the total density of states, the dielectric function, the extinction coefficient and the refractive index have been calculatedfor Lead Zirconate......
Petrogenesis of Subvolcanic rocks from the Khunik Prospecting Area, South of Birjand, Iran: Geochemical, Sr-Nd Isotopic and U-Pb Zircon Constraints
ratios (0.704196–0.704772) and εNdi values (+1.3 to +3.3) are compatible with an origin of the parental melts in a supra-subduction mantle wedge. Zircon U–Pb dating by LA-ICP-MS indicates the age of 38±1 Ma (late Eocene) for subvolcanic units...
U–Pb zircon geochronology, petrochemical and Sr–Nd isotopic characteristic of Late Neoproterozoic granitoid of the Bornaward Complex (Bardaskan-NE Iran)
ages (Jurassic, Cretaceous or even younger ages) by many studies. In the present study, new isotopic information based on zircon U–Pb dating has revealed the origin and time of the formation of the BGC. These new results do not confirm previously...
بررسی زمین شناسی، دگرسانی، کانی سازی و ژئوشیمی در گستره ی پی جویی دهن قلعه، شمال غربی بردسکن
گستره ی پی جویی دهن قلعه، در فاصله ی حدود 300 کیلومتری جنوب غربی مشهد واقع شده و از نظر تقسیم بندی، پهنه های زمین ساختی، بخشی از پهنه ی زمین ساختی تکنار است. این پهنه به واسطه ی گسل تکنار از پهنه ی زمین ساختی سبزوار در ...
