摘要：
An optical sensor membrane for the determination of chloride is described. It incorporates trioctyltin chloride as an ionophore and a chromoionophore in a plasticized PVC matrix. The concentration of chloride is indicated by co-extraction of chloride and hydrogen ions into the bulk of the membrane yielding large absorbance changes which can easily be measured in the visible spectral range. The performance of this sensor and its application to chloride determinations in human plasma are reported.
