| Abstract: | Abstract: A new method of extractive-photometric determination of trace potassium with dibcnro 18-crown-6 and dipicrylainc is described. The molar absorptivity approaches to 4x 104(420nm). The method has been applied in the de-termination of K+in ground water, rock, soil and plant samples. |
