CdS-intercalated Bentonite: A Novel Sulfide Ion Selective Electrode

摘要

CdS-intercalated bentonite was prepared by an in situ solid-solid reaction and mixed with artificial graphite, polytetrafluoroethylene (PTFE) and carboxymethyl cellulose (CMC) in an appropriate ratio to construct a novel, potentiometric sulfide ion selective electrode. Apart from its good selectivity, the electrode is low cost and good precision.
