Adsorption of the heavy metal ions onto biosorbents: A review
Heavy metal pollution in result of human activities such as mining has become a critical environmental issue nowadays. Various methods for removing heavy metal from industrial wastewater have been investigated. This paper reviews an economic and environment friendly process known as biosorption. Biosorption is a potential alternative to the conventional treatment processes such as adsorption on activated carbon. Some factors ... 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

Removal of Toxic Pb(II) Ions from Aqueous Solution by Nano Sized Flamboyant Pod (Delonix regia)
The removing of toxic heavy metals from aqueous solution by agricultural biosorbents was investigated by studying the effect of nano sized (Delonix regia) and chemically modified biosorbent citric acid Delonix regia (CADR) for removing of Pb2+ ions. TEM, XRD and EDS, FT-IR, SEM methods were used for characterizing the biosorbent(Delonix regia). The effect of contact time, pH,temperature, dosage of biosorbent, ... إقراء المزيد
