摘要: The invention relates to methods of determining potassium ions in a sample, wherein the are contacted with compound having chromophoric moiety and an ionophoric moiety, where interacts present resulting changing its radiation absorption properties ultraviolet visible regions spectrum. For example, change intensity maximum is measured ion concentration determined accordingly.
