摘要：

Properties of three derivatives of trifluoacetophenone [4-(n-butyl)-1-trifluoroacetylbenzene (BTFAB), 4-(n-hexadecyl)-1-trifluoroacetylbenzene (HDTFAB), p-dodecyloxytrifluoroacetylbenzene (DDTPAB)] as neutral carriers for carbonate were examined. The best electrode characteristic (slope, S = 29 mV decade(-1), lowest detection limit) was for HDTFAB, The sensitivity towards carbonates was for DDTFAB pH dependent, This eliminates DDTFAB from practical applications, A theoretical treatment concerning carbonate and hydrogencarbonate selectivity under investigated conditions has been performed, Preliminary determination of carbonate in bovine serum was made using electrodes with HDTFAB.
