Efficient removal of Eriochrome black-T from aqueous solution using NiFe2O4 magnetic nanoparticles
The magnetic NiFe2O4 nanoparticles have been synthesized and used as adsorbents for removal of an azo dye, Eriochrome black-T (EBT) from aqueous solution. The NiFe2O4 nanoparticles were characterized by scanning electron microscope (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectra (FTIR). The adsorption studies were carried out under v...
متن کاملSpent Tea Leaves as a Potential Low-cost Adsorbent for the Removal of Azo Dyes from Wastewater
Spent tea leaves (STL), a solid waste that is available in large amounts worldwide, was investigated as a potential low-cost adsorbent for the removal of two azo dyes, Reactive Green 19 (RG19) and Reactive Violet 5 (RV5), from contaminated waters. Preliminary experiments conducted on untreated STL showed that this material exhibited very low removal efficiencies (<10 %). By contrast, thermal ac...
متن کاملMercury removal from aqueous solutions by palm leaves adsorbent
Mercury is a carcinogenic and teratogenic compound that tends to accumulate in water solutions. In this research, the removal of mercury from an aqueous solution was evaluated by using palm leaves. Experiments were performed to study the adsorption efficiency, the effect of the adsorbent amount, the balance time, the adsorbate concentration, and the pH on mercury removal. The experimental appar...
متن کاملThe Perlite-calcium Alginate-activated Carbon Composite as an Efficient Adsorbent for the Removal of Dyes from Aqueous Solutions
To remove dyes from wastewater, the perlite-calcium alginate–activated carbon (PCA) composite was prepared by a simple method. This composite was characterized by FTIR, XRD, SEM, and BET techniques. A high capacity of PCA was observed for the adsorption of some dyes such as methylene blue (MB) and methyl orange (MO) from aqueous solutions (1111 and 909 mg g-1). The best results were achieved at...
متن کاملCoal Ash as a Low Cost Adsorbent for the Removal of Xylenol Orange from Aqueous Solution
The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...
