    Metal chelating activity of Centella asiatica by Mohd Salim, Roshan Jahn, Amid, Azura, Adenan, Mohd Ilham, Sued, Anee Suryani

    Published 2010
    “…The metal chelating potency can be determined by assessing the ability of neuroprotective agents to compete with ferrozine for Fe(II) ions. Ferrozine forms complexes with Fe(II) producing a red color that can be measured quantitatively at 562 nm and addition of iron chelators interferes with the formation of ferrous and ferrozine complexes in a concentration-dependent manner. …”

    Evaluation of solid-state bioconversion of domestic wastewater sludge as a promising environmental-friendly disposal technique by Molla , Abul Hossain, Fakhru’l-Razi, Ahmadun, Alam, Md. Zahangir

    Published 2004
    “…The final pH drop was higher in the CB than the F, which implied that a higher nitrification occurred in the CB associated with a higher release of H+ ions. Both the mixed cultures performed almost equal roles in all cases except the changes in moisture content.…”
