A PVC membrane electrode based on upper-rim calix[4]crown as ionophore was prepared using dioctyl sebacate (DOS) as a plasticizer. The potential response of this membrane electrode to alkali, alkaline earth metal cations were examined. This membrane electrode exhibited a Nemstian response to <TEX>$10^{-5}-10^{-1}M$</TEX> of CsCI with a slope of 52.3 mV/decade in Tris-buffer(pH 7.20). Its response time (<TEX>$t_{90%}$</TEX>) was 10s and it could be used for at least 2 months.
