RISPreparation of magnetic photocatalyst nanohybrid decorated by polyoxometalate for the degradation of a pharmaceutical pollutant under solar light
Magnetic polyoxometalate nanohybrid was prepared by the surface modification of γ-Fe2O3/SrCO3 nanoparticles with PW12O40 3 − polyoxometalate (POM) anions. The results of Fourier transform infrared (FTIR) and energydispersive ...
A new approach for the preparation of magnetic-polyoxometalate nanocomposite and its photocatalytic activity under sunlight
Over recent years. nanocomposites hove considerable attention due to
synergistic properties of initial compounds and their application in functional materials.
The aim of this work was the investigation ...
Effect of adsorbents and chemical treatments on the removal of strontium from aqueous solutions
In the present investigation, three different solid wastes namely almond green hull, eggplant hull, and moss were initially treated and used as adsorbents for the adsorption of strontium ion from aqueous solutions. Adsorbent ...
Influences of spinel type and polymeric surfactants on the size evolution of colloidal magnetic nanocrystals (MFe2O4, M = Fe, Mn)
Two types of polymeric surfactants, PEG300 and PVP40000, were used for the preparation of magnetic
ferrite MFe2O4(M = Mn, Fe) colloidal nanocrystals using a solvothermal reaction method. The effect of spinel type ...
بررسی روشهای اصلاح ساختار سطح نانوذرات مغناطیسی اکسیدآهن به منظور کاربرد در دارو رسانی هدفمند
بسیاری از محدودیت ها و مشکلات روش های متداول درمان سرطان از جمله شیمی درمانی و پرتو درمانی، در اثر عدم وجود هدف مشخص در حین دارورسانی به وجود می آید. لذا در سالهای اخیر ، سیستم های دارورسانی هدفمندی طراحی شده اند که دارای ...
Synthesis and application of diethanolamine-functionalized polystyrene as a new sorbent for the removal of p-toluenesulfonic acid from aqueous solution
Polystyrene resin was functionalized by diethanolamine for the efficient removal of p-toluenesulfonic
acid (p-TSA) from aqueous solution. Functionalized adsorbent (DEA-PS) was characterized by elemental
analysis, ...
