Modification of silica nanoparticles by 2,4-dihydroxybenzaldehyde and 5-bromosalicylaldehyde as new nanocomposites for efficient removal and preconcentration of Cu(ii) and Cd(ii) ions from water, blood, and fish muscles

Abstract

Herein, silica nanoparticles were modified by 2,4-dihydroxybenzaldehyde and 5-bromosalicylaldehyde to produce new nanocomposites which were abbreviated as N1 and N2, respectively.

Facile synthesis and characterization of magnesium and manganese mixed oxides for the efficient removal of tartrazine dye from aqueous media

“…[7][8][9][10][11][12][13][14][15] However, adsorption is the most important method for removing non-degradable and persistent pollutants from wastewater because it is more economically and ecologically advantageous than other methods. [16][17][18][19][20][21][22] Nanomaterials had attracted considerable interest in the area of adsorption because of their unique characteristics of small size, enhanced porosity, and increased surface area. [23][24][25][26][27][28][29][30][31][32] The Pechini sol-gel method is preferable to other methods used to prepare metal oxide nanoparticles.…”
