Toxic Industrial Chemical Removal by Isostructural Metal-organic Frameworks

Applications of goethite nanoparticles for removal of arsenic and mercury toxic ions from synthetic wastewater

Contamination of water resources with toxic elements is one of the challenges of thetoday's world. In this research, application of Goethite nanoparticles in removingcontamination of arsenic and mercury from synthetic wastewater in a batch mode isinvestigated. For this purpose, the effect of different factors including pH, adsorbent dosage,contac...

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

UV spectrophotometry for monitoring toxic gases

The need for gas compound measurement concerns overall three domains: environmental monitoring, emission measurement and risk assessment. These fields are different because of concentration range (from 10–3 to thousands mg.m–3). A fast technique has been developed based on UV spectrophotometry. Simple robust optics and absence of interference from water vapour and carbon dioxide are two of the ...

Three toxic gases meet in the mitochondria

The rationale of the study was two-fold: (i) develop a functional synthetic model of the Cytochrome c oxidase (CcO) active site, (ii) use it as a convenient tool to understand or predict the outcome of the reaction of CcO with ligands (physiologically relevant gases and other ligands). At physiological pH and potential, the model catalyzes the 4-electron reduction of oxygen. This model was immo...
