Determination of blood ph by potentiometry
WebCyanide is an extremely severe poison that has been raising concerns and controversies regarding its toxic effects on humans and the environment. A short-term human exposure to elevated levels can induce coma or death. Toxic effects occur at blood cyanide concentrations of 0.05 mg/dL, while death can occur at levels of 0.3 mg/dL. Numerous … WebCa2+ in serum, plasma, whole blood, and other biological fluids can be measured by direct potentiometry with ion-selective electrodes and a number of reliable instruments are commercially available for this measurement. Several factors affect the Ca2+ concentration and must be carefully controlled for the results to be meaningful.
