Removal of heavy metal ions from aqueous solution by modified Magnetic nano particles with aminoFA groups

Removal of heavy metal ions from aqueous solution by modified Magnetic nano particles with amino/FA groups

Removal of heavy metal ions from aqueous solution by modified Magnetic nano particles with amino/FA groups

In recent years, the spinel ferrite nanoparticles due to various applications in both fundamental and have been a lot of interest. In this work, magnetic (Fe3O4) nanoparticles chloride salts deposited using both two-and trivalent manganese and iron were produced in an alkaline environment. The surface layer of silica nanoparticles with improved chemical stability and improved dispersion in the reaction medium were covered. Where the hydrolysis of Tetraethyl orthosilicate (TEOS) was used, which ...

Removal of acid red 151 dye from aqueous solution using palm shell by adsorption: Isotherm Adsorption studies

The objective of this research is removal of Acid Red 151(A.R.151) from aqueous solutionusing palm shell as low-cost adsorbent. The operating parameters such as pH solution, doseof adsorbent, initial dye concentration were investigated. Results showed that pH: 3, dose ofadsorbent: 2g/L and initial dye concentration: 20mg/L were the most suitable. In this study,the best fit of the adsorption isotherm data was obtained using the Langmuir model and showfavorable adsorption of A.R.151 dye with ...
