摘要：

Reasoning from the regularities of the variation of electrochemical properties of sensors based on alkylpyridinium alkylsulfates (n = 10-15), we demonstrated that detection limits for surfactants are related to the solubility of ionophores. The slopes of electrode functions, selectivity, apparent extraction and dissociation constants of ionophores are governed by the hydrophobicity of the active components of membranes.
