RISحذف مخلوط یون های فلزی سرب، نیکل و کادمیم از محلولهای آبی با استفاده از جاذب نانوحفره MCM-41 اصلاح شده
گروهی از جاذبهای سیلیکاتی میان حفره تحت عنوان MCM-41 که مساحت سطح زیادی دارند، با اصلاح برخی از گروههای عاملی سطحی توسط گروه های آمین و ایجاد گونه اصلاح شده NH2-MCM-41، به ظرفیت جذب بالاتری برای جذب یون های فلزات سنگین دست ...
Selective adsorption of Pb(II), Cd(II), and Ni(II) ions from aqueous solution using chitosan–MAA nanoparticles
Chitosan–MAA nanoparticles (CS–MAA) with an average size of 10–70 nm were prepared by polymerizing chitosan with methacrylic acid in aqueous solution. The physicochemical properties of nanoparticles were investigated using ...
Controllable Synthesis of Flower-Like ZnO Nanostructure with Hydrothermal Method
Flower-like ZnO nanostructures were synthesized by decomposing Zn(OH)2 in 1,4- butanediol at 105 °C for 36 h. Size of flower-like ZnO nanostructure can be controlled by pH of the aqueous solution. In the preparation of ...
Removal of Ni(II), Cd(II), and Pb(II) from a ternary aqueous solution by amino functionalized mesoporous and nano mesoporous silica
In the present study, the application for the removal of Ni(II), Cd(II) and Pb(II) ions from aqueous solution by using mesoporous silica materials, namely, MCM-41, nanoparticle of MCM-41, NH2-MCM-41 (amino functionalized ...
