The magnesium ion content of a sample is determined by contacting the sample with a magnesium ion selective membrane including a 1,10-phenanthroline having an H group at positions 2 and 9. Examples of preferred 1,10-phenanthrolines include 4,7-diphenyl-1,10-phenanthroline, N-dodecyl-N-methyl-1,10-phenanthroline-4-carboxamide, 4-undecyl-1,10-phenanthroline, 4,7-diundecyl-1,10-phenanthroline and 5-nonyl-1,10-phenanthroline-4-carboxylate.
一种样品的镁离子含量是通过将样品与包括在镁离子选择性膜中的1,10-邻菲啰啉接触来确定的,其中在2和9位具有H基团。首选的1,10-邻菲啰啉的示例包括4,7-二苯基-1,10-邻菲啰啉,N-十二烷基-N-甲基-1,10-邻菲啰啉-4-羧酰胺,4-十一烷基-1,10-邻菲啰啉,4,7-二十二烷基-1,10-邻菲啰啉和5-壬基-1,10-邻菲啰啉-4-羧酸酯。
