Abstract
A study of interferences in the colorimetric determination of potassium, extracted as ion-pair [K-18-crown-6]+ picrate- in the toluene-methylene chloride (80:20) solvent mixture, was carried out. The species examined were those likely to be found, together with the K ion, in typical pharmaceutical formulations, namely, organic bases and inorganic cations.
摘要
开展了一项关于比色法测定钾时干扰情况的研究。钾以离子对[K - 18 - 冠 - 6]+苦味酸盐的形式在甲苯 - 二氯甲烷（80:20）混合溶剂中萃取。所检测的物质是那些在典型药物制剂中可能与钾离子一同存在的物质，即有机碱和无机阳离子。
