متن کاملDispersion of Cd , Cr , Cu , Ni , Pb and Zn Particles in a Turbulent Air Flow
From the prospective of air quality, the dispersion of heavy metal pollutants has gain importance in recent past. The pollutants disperse from the point of release to the distant areas transporting contaminants there. Heavy metal pollutants in the form of fine particulate matter can be harmful to human health through inhalation. In this study the lateral dispersion of heavy particles is predict...
متن کاملبررسی آب‌زمین‌شیمی و منشا فلزات بالقوه سمی(Cu, Pb, Zn, Cd, Cr, Ni) در رودخانه زایندهرود
به منظور بررسی کیفیت رودخانه زایندهرود، از آب و رسوبات این رودخانه در محدودهای به شعاع 50 کیلومتر از مرکز اصفهان، نمونهبرداری شد. محاسبه ضرایب شاخص نفوذپذیری، و نسبت جذب سدیم و نیز نمودار ویلکاکس نشان میدهد که کیفیت آب رودخانه زایندهرود برای مصارف کشاورزی مناسب است. شاخص اشباعشدگی(SI) نیز کیفیت مناسب این رودخانه را برای مصارف صنعتی در بیشتر نقاط نشان داد. مقایسه پسابهای تخلیهشده از سه ت...
متن کاملRoom Temperature Oxidation of Al-Cu-Fe and Al-Cu-Fe-Cr Quasicrystals
We have investigated formation of oxides on quasicrystalline and crystalline alloy surfaces of similar composition, in different oxidizing environments. This includes a comparison between a quaternary orthorhombic approximate of Al-Cu-Fe-Cr quasicrystal and the ternary AI-Cu-Fe quasicrystalline and crystalline phases. We noted that each sample showed the following common trends: preferential ox...
