研制了文献上尚未见有报导的顺式—二苦胺基二苯并—18—冠—6.用此生色冠醚在四氢呋喃中作钾的光度测定,0—100微克范围内,△A—[K~+]作图有良好的线性关系.反应灵敏度比同类型的4’—苦胺基苯并—15—冠—5测定钾的方法高12倍(Sandell系数为0.028μg/cm~2)。
The literature has not yet been reported on cis-didecyl-dibenzo-18-crown-6 with this color crown ether in tetrahydrofuran for potassium photometry, 0-100 micrograms range, △ A- [K ~ +] showed a good linear relationship.The reaction sensitivity was 12 times higher than the method of potassium determination with the same type of 4’-Kuraminobenzo-15-crown-5 (Sandell’s coefficient was 0.028μg / cm ~ 2 ).
