Removal of Lead Ions from Aqueous Solution by Sorptive-Flotation Using Limestone and Oleic Acid
A simple, rapid and economic procedure was presented to remove lead(II) from aqueous solution under the optimized conditions. It is based on the sorption of Pb2+ ions from aqueous solutions onto limestone fines (LS), which is an inexpensive and widespread over the globe, followed by flotation with oleic acid (HOL) surfactant. The different parameters (namely: solution pH, sorbent...
متن کاملRemoval of Cadmium and Lead Ions from Aqueous Solution by Nanocrystalline Magnetite Through Mechanochemical Activation
In this study, the removal of cadmium and lead ions from aqueous solution by nanocrystalline magnetite was investigated. The nanocrystalline magnetite was synthesized by mechanochemical activation of hematite in a high energy planetary mill in argon atmosphere for 45 hours. The ability of the synthesized nanocrystalline magnetite for removal of Cd(II) and Pb(II) from aqueous solutions was studi...
متن کاملRemoval of copper ions from aqueous solutions using polypyrrole and its nanocomposites
In this article, preparation of polypyrrole and its nanocomposites as adsorbents werediscussed and the capability of separation of copper ions from aqueous solution were studied.Polypyrrole was prepared by chemical oxidative polymerization method of pyrrole usingFeCl3 as an oxidant. The removal of Cu (II) was investigated using PPy, PPy/TiO2 andPPy/TiO2/DHSNa nanocomposites. The products were i...

چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...
15 صفحه اولHeavy metals removal from wastewater by using different kinds of magnetite nanoadsorbents: effects of different organic and inorganic coatings on the removal of copper and lead ions
Co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of Pb(II) and Cu(II) toxic metal ions from wastewater samples. Prepared nanoadsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The average sizes of t...
