Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] An embodiment of the present invention provides a magnesium ion selective membrane. When the magnesium ion selective membrane and a reference electrode are simultaneously immersed in a liquid solution, a potential is formed between the magnesium ion selective membrane and the reference electrode. The potential is proportional to the logarithm of the concentration of magnesium ions in the solution, and the concentration of magnesium ions in the solution can be obtained by measuring the potential with a potential measuring device such as a potentiometer.
[0029] The magnesium ion selective...

Abstract
The embodiment of the invention relates to the technical field of chemical analysis, in particular to a magnesium ion selective membrane, a preparation method and an electrolyte analysis system. The magnesium ion selective membrane comprises: an ion carrier comprising 4, 7-diphenyl-1, 10-phenanthroline with a content of 3.5%; a first additive which is prepared from 0.5 to 1.5 percent of bis [4-(1,1, 3, 3-tetramethylbutyl) phenyl] semi-calcium phosphate; a second additive which is prepared from 4.5% of L-ascorbic acid and 2-sesquicarbonate hydrate; a plasticizer which is prepared from o-nitrophenyl octyl ether with the content being 61 percent to 62 percent; and a polymer matrix which comprises polyvinyl chloride with the content of 29.5%-29.7%. The magnesium ion selective membrane is goodin selectivity linearity and sensitivity to magnesium ions, good in selectivity to the magnesium ions and long in service life.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of chemical analysis, in particular to a magnesium ion selective membrane, a preparation method and an electrolyte analysis system. Background technique [0002] Magnesium is one of the most abundant cations in the body. Determining blood magnesium can tell whether there is magnesium deficiency in the body. Decreased blood magnesium concentration can lead to increased neuromuscular excitability, convulsions, rigidity, hyperreflexia, disorientation and other symptoms. Elevated blood magnesium concentration may cause symptoms of neuromuscular excitability inhibition, such as nausea, drowsiness, hypotension, and respiratory depression. Hypermagnesemia can cause prolonged atrioventricular conduction time. Therefore, the detection of blood total magnesium and free magnesium is of great significance in medicine. [0003] In the past, a variety of methods and techniques have been used t...
