Adsorption of heavy metal ions by immobilized phytic acid
Applied Biochemistry and Biotechnology, 1997Phytic acid (myoinositol hexaphosphate) or its calcium salt, phytate, is an important plant constituent. It accounts for up to 85% of total phosphorus in cereals and legumes. Phytic acid has 12 replaceable protons in the phytic molecule, rendering it the ability to complex with multivalent cations and positively charged proteins. Poly 4-vinyl pyridine (

Heavy metal contamination in ion implantation
AIP Conference Proceedings, 1997Reduction of metallic contamination during ion implantation is becoming increasingly critical for device performance. Modern implanters are being developed with novel beamline coating materials and optics to keep sputtered contamination to a minimum. However chemical processes occur in the implanter which lead to contaminants being deposited onto the ...

Removal of heavy metal ions by nanofiltration
Desalination, 2013Abstract This study describes the rejection of heavy metal ions using a commercial nanofiltration membrane (NF270). The effect of feed pH, pressure and metal concentration on the metal rejections and permeate flux and in some cases permeate pH was explored.

ADSORPTION OF HEAVY METAL IONS BY POPLAR SAWDUST
2007Decontamination of synthetic Ni(II), Cd(II) and Pb(II) Solutions using poplar sawdust Was investigated. Batch sorption studies have been carried Out to determine the effect of contact time, temperature and initial Concentration of heavy metal ions (HMI) on adsorption. Equilibrium time was found to be around 60 min.

The Interaction of Heavy Metal Ions with DNA
1995The effect of metal ions upon conformation of DNA was realized early, when it became apparent that metal ions are involved in the stabilization of the Watson-Crick double helix1,2. Metal ions react with a variety of electron-donor sites on polynucleotides3. There are two main sites of interaction, the phosphate moieties of the ribose-phosphate backbone

[Advances in heavy metal ions immunoassay].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2010Heavy metal leftover on farm and stock products has become a big threat to human. It is necessary to develop some fast and efficient detection methods. Heavy metal immunoassays are new methods for detection of heavy metal ions. Compared to the traditional chemical methods, immunoassays are not only fast, cheap, simple, but also reasonably portable ...
