Sulfo and carboxyl group-containing polymers polymer/silica adsorbents poly(acrylonitrile-co-2-acrylamido-2-methylpropane-1-sulfonic acid-co-acrylic acid-co-N,N’-methylene-bis-acrylamide) [poly(AN-co-AMPS-co-AAco-MBA)] poly(AN-co-AMPS-co-AA-co-MBA)/SiO2 were synthesized by a UV-initiated polymerization or simultaneous in situ sol-gel process used as for removal of Co(II) Ni(II) ions from aqueou...
Background and Objectives: Increased growing nuclear industry has increased the researchers concerns on uranium presence in the environment and its effects on human health. Uranium is a dangerous radioactive heavy metal with high half-life and chemical toxicity. Therefore, the main objective of this study was to removal uranium (VI) from aqueous solution by uranium benzamide complex using AC_Fe...
Heterogeneous catalysts have been widely used for peroxymonosulfate (PMS) activation to remove persistent contaminants in water. This study successfully prepared cobalt-doped TiO2 using a simple two-step approach activating PMS tetracycline (TC). The batch experiments showed complete TC degradation within 25 min caused by Co-TiO2 (0.1 g/L) of (1 mM) under visible light. system also demonstrated...
بررسی کارایی نانو ذرات مغناطیسی پوشش داده شده با پلیمر کاتیونی کیتوزان در حذف کدورت از محلولهای آبی
Abstract Introduction: Water turbidity is caused by some particles, organic compounds and microorganisms. This study aimed to evaluate the performance of magnetic nanoparticles coated with chitosan as a cationic polymer in turbidity removal from aqueous solution. Methods: In this empirical study, the chemical co-precipitation technique was used to synthesize the magnetic nanoparticles coa...
CO(2) sequestration by cyanobacteria and green algae are receiving increased attention in alleviating the impact of increasing CO(2) in the atmosphere. They, in addition to CO(2) capture, can produce renewable energy carriers such as carbon free energy hydrogen, bioethanol, biodiesel and other valuable biomolecules. Biological fixation of CO(2) are greatly affected by the characteristics of the...
Carbon dioxide removal (CDR) is essential to deliver the climate objectives of Paris Agreement. Whilst several CDR pathways have been identified, they vary significantly in terms CO 2 efficiency, timing, and permanence.
background: in this study, ferrate (vi) and ultraviolet (uv) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (cod). although ferrate (vi) and uv have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of simultaneous...
