Determination of potassium ion concentration in serum

Aug 01, 1970 A simple method for the direct determination of the K + concentration in undiluted blood serum is described. The reproducibility of single determinations using the readings after 60-sec contact of a valinomycin liquid-membrane electrode with the sample is 0.07 mequiv/1 K + (standard deviation). No corrections are needed for the presence of other ions in the sample solutions.

Frontiers Regulation of K+ Nutrition in Plants Plant

Introduction. Potassium (K +) is of paramount importance in plant cell physiology.K + is an essential macronutrient that fulfills critical functions related to enzyme activation, osmotic adjustment, turgor generation, cell expansion, regulation of membrane electric potential, and pH homeostasis (Hawkesford et al., 2012).While the K + concentration in the soil solution may vary widely from 0.01
