Abstract
Abstract The stability constants of the Calcium ionophore I (i.e., N , N ´ – di[(11′- ethoxycarbonyl) undecyl] – N , N ′,4,5 -tetramethyl – 3,6 – dioxaoctane diamide) complexes with M n+ (M n+ = Li + , H 3 O + , Na + , NH 4 + , Ag + , K + , Rb + , Tl + , Cs + , Ca 2+ , Sr 2+ , Ba 2+ . Pb 2+ , Cu 2+ , Zn 2+ ) in nitrobenzene saturated with water were determined by the extraction method. These constants were found to increase in the series of Cs + < Rb + < K + < NH 4 + < Na + < Tl + < H 3 O + < Ag + < Li + and Ba 2+ < Zn 2+ < Sr 2+ < Pb 2+ < Cu 2+ < Ca 2+ .
