在某些生理过程中,钾有重要作用。临床检验中,血钾量是诊断某些疾病的依据。目前国内测定血清钾含量,一般多采用四苯硼钾浊度法或火焰光度法。藉钾离子选择电极测定血钾已有报道,国外已有专用仪器。小型钾电极能在小量液样中使用,可减少需要的血样量。我们曾用4,4-二叔丁基二苯并-30-王冠-10制成了有实用价值的钾电极并在此基础上于电极膜内加入适量的四苯硼钾,降低了膜内
In some physiological processes, potassium has an important role. Clinical tests, blood potassium is the basis for the diagnosis of certain diseases. At present, the determination of serum potassium content, the general use of potassium tetraphenylborate turbidimetry or flame photometry. Potassium potassium ion selective electrode determination of potassium has been reported, foreign special instruments. Small potassium electrodes can be used in small sample volumes to reduce the amount of blood sample required. We have used 4,4-di-tert-butyldibenzo-30-crown-10 made of practical value of the potassium electrode and on the basis of the electrode film in the right amount of tetraphenyl boron, reducing the film
