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 ...

EXTERACTION AND SEPARATION OF TRACE AMOUNTS MO (П) IN WATER SAMPLES USING NANO POLYHYDROXYBUTYRATE-B-POLYDIMETHYL SILOXANE

EXTERACTION AND SEPARATION OF TRACE AMOUNTS MO (П) IN WATER SAMPLES USING NANO POLYHYDROXYBUTYRATE-B-POLYDIMETHYL SILOXANE

In this method to amounting of the trace little amount of Mo (II) ions in aqueos Samples by Nano Polyhydroxybutyrate-b-polydimethyl siloxane which in order to improve the performance of extraction and preconcentration was used. Amounting of the ions density in solution was performed by the method of flame atomic absorption spectrometry. The effective parameters on extraction such as: effect of pH, the amount and eluent solvent, time of extraction and effect of other cation were optimized. ...
