Abstract:

Calcium ions play a key role in a number of physiological processes including blood coagulation, secretion, muscular contraction and intercellular communication. Hence, the monitoring of calcium in body fluids is of great importance in the diagnosis and prevention of various diseases. There have been a lot of methods dealing with the measurements of calcium in human serum and cerebrospinal fluids, among which atomic absorption spectrometry is considered to be the best one, but spectrophotometric methods are more often used because of their simplicity and low cost.
