A comparative study for the effect of nano-sized Moringa oleifera and Delonix regia for removal heavy ions from water
The ability of natural biosorbents for removing heavy metal ionswere investigated by studying the effect of nano sized _Delonixregia _and _Moringa__ oleifera_on adsorption of Cd2+and Pb2+ions from aqueous solution. The investigated biosorbents (_Delonixregia_and _Moringa__oleifera)_ were characterized by FT-IR, SEM, TEM, XRD and EDS techniques.The influence of pH, temperature, adsorbent dosage, contact time and initial metal ion concentration on adsorption process ... إقراء المزيد

Effect of chromium substitution on the structural and magnetic properties of nanocrystalline zinc ferrite
Single-phase Cr doped zinc ferrites have been synthesized by hydrothermal method. The crystal structure, microstructure, crystallite size and distribution, composition and magnetic properties of the synthesized nanoparticles were determined using X-ray powder diffraction, electron microscopies and vibrating sample magnetometry. Powders are composed of ultrafine spherical nanoparticles with a highly homogeneous elemental composition. The nanoparticles have partially inversed cubic spinel structure ... إقراء المزيد
