FAD: Matrices

Abstract: 2-Mercaptobenzimidazole loaded on silica gel (MBI-SG) was used for pre-concentration and speciation of iron(II) and iron(III) in water samples The speciation is based upon selective retention of iron(III) on MBI-SG sorbent and quantitatively passing iron(II) ions This type of sorbent was not only capable of separating theses two ions but also could

Synergistic inhibitive effect of cysteine and iodide ions

The synergistic inhibitive effect of cysteine (Cys) and iodide ions on the corrosion behavior of copper was examined in a 0 5 molL−1 Na2SO4 solution Potentiodynamic polarization curve revealed that Cys acted as a mixed type inhibitor with a major effect on the cathodic process consequently decreased the corrosion current density by a great extent and shifted the
