ABSTRACT:
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.
