ZnO/CdO nanocomposites for textile effluent degradation and electrochemical detection

New nanocomposites based on polyamide containing imine groups reinforced with functionalized polyethyleneimine‐modified ZnO nanoparticles; fabrication, characterization and lead ion adsorption studies

“…PEI has been used for surface modification of various nanoparticles for different applications , but grafted with silane organic compound for modification of the surface of ZnO nanoparticles has not been reported. Branched PEI as a multifunctional polymer due to its wide range of buffering capacities and using at broad range of pH in an aqueous solution has been used for trapping several types of heavy metals such as uranium, cadmium, lead, zinc, copper, and nickel . It was expected that due to interactions between amine groups in PEI structure and PA chain, a good compatibility occurred between PSMZ and the PA matrix.…”

Effective Removal of Azo Dye Reactive Blue 222 from Aqueous Solutions Using Modified Magnetic Nanoparticles with Sodium Alginate/Hydrogen Peroxide

“…Over seven million tons and approximately 10,000 different types of dyes and pigments are produced throughout the world every year by conventional industrial wastewaters . Industries such as textile, leather, rubber, plastics, and paper produce a high volume of dye‐laden effluents released into, without enough treatment, water resources; this leads to surface and groundwater contamination . Reactive dyes are one of the most common dyes that are used for dyeing cellulosic fibers due to their simple applications and low energy consumption .…”

Preparation of magnetic nanoparticles functionalized with poly (styrene‐2‐acrylamido‐2‐methyl propanesulfonic acid) as novel adsorbents for removal of pharmaceuticals from aqueous solutions

“…These processes include membrane technologies, [8,9] photocatalytic oxidation processes, [10][11][12][13][14][15][16][17][18] electrochemical oxidation, [19,20] chlorination, [21] coagulation-flocculation, [22] biodegradation, [23] and adsorption processes, [24][25][26][27][28][29][30] but the most of processes have several drawbacks such as production of hazardous by-products by degradation, chlorination and ozonation methods, [31] or fouling of membranes during filtration. These processes include membrane technologies, [8,9] photocatalytic oxidation processes, [10][11][12][13][14][15][16][17][18] electrochemical oxidation, [19,20] chlorination, [21] coagulation-flocculation, [22] biodegradation, [23] and adsorption processes, [24][25][26][27][28][29]…”
