Research output: Contribution to journalArticle


A new, simple and fast spectrophotometric method for the determination of the H2S concentration is reported. This method, based on the 1:1 reaction between H2S and the ferric derivative of hemoglobin I (HbI) from the bivalve mollusc Lucina pectinata, allows the quantitative determination of H2S dissolved in a given solution even at concentrations as low as 1 x 10-6 M. Note that L. pectinata HbI is considered the physiological receptor of H2S. (C) 2000 Elsevier Science B.V.
