Potassium has an essential function in physiological systems, especially in transporting molecules across the cell membrane. The potassium pump is important in maintaining the equilibrium between the interior of the cells and the surrounding interstitial fluid. This is vital in transferring electrical signals through muscles and sustaining a regular heartbeat. When the lithium ion competes with potassium ion, it interferes with this equilibrium. Lithium may also substitute for potassium in nerve tissues that conduct electrical stimulation to muscles.

This results in muscle cramps and pain. Depletion of Potassium Levels An electrolyte is a substance that breaks down to an ionized form in water and allows the body to conduct electrical stimuli to muscles.

An important electrolyte in the human body is potassium. We get potassium in our bodies generally from dietary sources such as bananas, Brussels sprouts, yogurt, milk, soy products, beans, peanut butter, chicken, beef, fish, citrus fruits and peaches. These trace elements have the same valence charge, which allows lithium to actively compete with potassium and often replace it in biochemical reactions in the body.

When lithium replaces these elements in biochemical reactions, it alters the overall physiology as it affects electrolyte gradients on both sides of the cell membranes.

Lithium & Low Potassium Levels | Sciencing

Lithium diffuses into red blood cells which carry it throughout the body in the vascular system. It attaches itself to binding sites on nerve tissues and can change the electrical impulse conduction and the complex electrolyte balance. This eventually causes fatigue and other muscle problems.

As lithium replaces potassium, the kidneys remove the potassium ions from the body and further electrolytic imbalance ensues as potassium declines. Elemental Analysis of Zeolites For the analyst who prefers a fusion over acid digestion, it is recommended that Li ores and minerals be fused with high purity Please see the following article for more detailed information concerning carbonate fusions: Dissolve the sample in water using a slight excess of nitric acid and dilute to a specified volume.

In the case of alkali carbonates, the solution should be boiled after acidification to expel carbon dioxide before making to volume. The presence of dissolved carbon dioxide or other gases can cause poor precision due to gas bubble formation in some nebulizers during sample introduction.

Organic Matrices This includes a wide variety of materials including fertilizers, agricultural material, organic plant material, biological material, synthetic organics, etc. The crucible can be a variety of materials including Pt, quartz, fused silica, porcelain, or glassy carbon. Samples high in Li or K will attack Pt and all of the alkali metal oxides attack silica, quartz and the silica glaze on porcelain.

Samples Containing Lithium, Sodium, Potassium, Rubidium or Cesium

It is always suggested that the sample be treated with sulfuric acid either before charring or just after charring and before muffling, which eliminates alkali oxide formation during muffling and consequently alkali attack on the crucible. It is best to use a minimum of sulfuric since the goal is to encourage sulfate formation but rid the sample of all excess sulfuric acid before placing in a muffle furnace, otherwise the formation of SO3 will contaminate the air.

The alkali sulfates can tolerate higher temperatures, but there is no need to push limits.

The following is a general outline for performing a wet ash or sulfated ash: Wet Ash Weigh the sample into your crucible typically porcelain and then wet the sample with concentrated sulfuric acid. Only add enough sulfuric acid to just wet the sample. Excess sulfuric acid will require extra time in fuming off before placing in a muffle furnace to achieve ashing temperatures. Place the sample on a hot plate and heat until the fumes of sulfuric acid dense white fumes stop.

Carbonaceous material is typically signaled by the formation of coke-like material that is black in color. The appearance of the ash should lighten and will approach white to tan over time.

If certain transition elements are present, the color may appear to get darker with time due to the formation of the transition metal oxides Ni and Co oxides are very dark.

If this occurs, the sample will need to be "resulfated" - cooled and wetted with sulfuric acid - in order to avoid the difficulties encountered with the dissolution of ignited transition metal oxides. Sulfate Ash Weigh the sample in the crucible and char it on a hot plate. After charring, wet the char with sulfuric acid. This typically takes only drops of the concentrated acid.

Consult the Ashing portion of our Trace Analysis Guide for more information on ashing techniques. In addition the use of any mineral acid, water or caustic, is acceptable with the following exceptions.

For K, Rb and Cs, avoid chloroplatinate, acid Tartrate, fluorosilicate, picrate, phosphomolybdate, perchlorate, periodate, fluorotitanate, fluorozirconate. For Na, avoid the fluorosilicate. All Li salts are soluble. Attempt to use LDPE that has been pre-leached with dilute nitric acid as the container material whenever possible.

Avoid glass due to the possibility of contamination with Na.
