Abstract

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.
