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

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 ...

A radial basis function (RBF) and collocation method with for solving the modified equal width equation

In this paper, we examined the global collocation method using standard types ofradial basis function for numerical solution of the modified equal width (MEW)equation. The propagation of single solitons and the interaction of two solitary wavesare used to validate the method which is found to be accurate and efficient. ...

Solving Vibration Equations of MDOF Systems by Modified Differential Transform Method

Solving Vibration Equations of MDOF Systems by Modified Differential Transform Method

Vibration equations of discrete multi-degrees-of-freedom (MDOF)structural systems is system of differential equations. In linear systems,the differential equations are also linear. Various analytical andnumerical methods are available for solving the vibration equations instructural dynamics. In this paper modified differential transformmethod (MDTM) as a semi-analytical approach is generalized for thesystem of differential equations and is utilized for solving the vibrationequations of MDOF ...
