摘要: The effect of ultrasonic decomposition was introduced to develop a pretreatment method for the analysis potassium ion in human urine by potentiometry. N-(4’-benzo-15-crown-5)-anthracene-9-imine, which has good selectivity coefficient against ammonium, used as an ion-selective material determination with relatively high concentration . Protenis be removed 85.1% when sample acidified 1.0 M preteated 100 s sonication. Potential response membrane electrode pretreated had slope 54.6(${\pm}0.2,\;n
