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

Kinetic study of the base-catalyzed hydrolysis of novel high-spin hydrophobic Fe(II)-azomethine amino acid chelates: Salt and structure effects on the reactivity
The effect of salts on reactivity of basic hydrolysis of Fe(II) chelates bis(naphthylidenealanate) (nali), bis(naphthylidenephenylalanate) (nphali), bis(naphthylideneaspartate) (nasi), (naphthylidene histidinate) (nhi), bis(naphthylidene arginate) (nari) has been studied in aqueous media containing alkali metal halides, LiBr, NaCl, KBr, tetramethylammonium bromide (TMAB), tetraethylammonium bromide (TEAB), and tetrabutylammonium bromide (TBAB). The suggested mechanism of the base hydrolysis involves the parallel attack of OH−ions ... إقراء المزيد
