Disposal of Heavy Transition Cd(II) ions from Aqueous Solution utilizing Nano Sized Flamboyant Pod (Delonix regia)
The absorption of toxic heavy metal by natural adsorbents from water were indicated by investigation the effect of nano sized (_Delonix regia _(DR)) and (CADR) citric acid_ Delonix regia_ chemically modified adsorbent for removing the Cd2+ ions. Different techniques were employed for characterizing the adsorbent (_Delonix regia_) such energy dispersive analysis of X-ray (EDAX), Fourier transform infrared spectroscopy (FT-IR), Transmission ... إقراء المزيد

Nano sized ternary Cu(II) complexes Encompassing Salicylaldehyde Derivatives and Amino Acids as an Effective Strategy for Antimicrobial Activity Improvement and DNA Interaction
A series of ternary Cu(II) complexes encompassing ONO donor Schiff base amino acid ligands were synthesized from condensation of 3–methoxysalicylaldehyde (MS) or 4-diethylamino salicylaldehyde (DS) with α-amino acids (L-phenylalanine (Phe), L-histidine (His), DL-tryptophan (Trp)) as primary ligand and 2, 4-bipridyl (DP) as secondary ligand. All the prepared compounds were characterized by melting points, decomposition temperatures, elemental analysis, UV-Vis, IR spectra, ... إقراء المزيد

Removal of Cd(II) ions From Aqueous Solution using Nano sized Moringa Oleifera
This research aims to study the effect of nano sized _Moringa oleifera_ on adsorption of Cd2+ ions from aqueous solution. The investigated biosorbent was characterized by FTIR, SEM, TEM, XRD and EDS techniques. The influence of pH, temperature, adsorbent dosage, contact time, metal ion concentration and chemical treatment of biomass were investigated. The maximum capacity (qm) of Cd2+ ions biosorption ... إقراء المزيد

Nano Sized Moringa oleifera an Effective Strategy for Pb(II) ions Removal from Aqueous Solution
Nano-sized _Moringa oleifera_ is considered an effective biosorbent with high surface area from agricultural waste, low coast and environment-friendly which can be used for removal of Pb2+ from waste water. Thus our study stem to investigate the ability of natural nano-sized biosorbents for removing very toxic Pb2+ ions from aqueous solution. The investigated biosorbent (_Moringa oleifera_)was characterized by FTIR, SEM, ... إقراء المزيد
