One-Step Room-Temperature Synthesis of Bimetallic Nanoscale Zero-Valent FeCo by Hydrazine Reduction: Effect of Metal Salts and Application in Contaminated Water Treatment

Autor: Asmaa A. Koryam, Shaimaa T. El-Wakeel, Emad K. Radwan, Elham S. Darwish, Azza M. Abdel Fattah

Publikováno v: ACS Omega. 7:34810-34823

The effect of initial salt composition on the formation of zero-valent bimetallic FeCo was investigated in this work. Pure crystalline zero-valent FeCo nanoparticles (NPs) were obtained using either chloride or nitrate salts of both metals. Smaller N

Preparation and characterization of chemically cross-linked zwitterionic copolymer hydrogel for direct dye and toxic trace metal removal from aqueous medium

Autor: Asmaa A. Koryam, Shaimaa T. El-Wakeel, Emad K. Radwan, Azza M. Abdel Fattah, Elham S. Darwish

Publikováno v: Environmental Science and Pollution Research.

In this work, a zwitterionic copolymer hydrogel with adsorption affinity toward anionic dye and cationic trace metal was prepared by a free radical copolymerization of cationic ([3-(methacryloylamino)propyl] trimethylammonium chloride (MPTC)) and ani
