| תקציר≠ | Potentiometric titration is an electrochemical method of analysis that measures the potential difference between a reference electrode and an indicator electrode as a titrant is gradually added to a solution. Developed in the early 20th century, it allows precise determination of the concentration of analytes without requiring visual endpoint indicators. This method is fundamental in analytical chemistry for determining acids, bases, redox species, and metal ions. | Atomic absorption spectroscopy is an analytical technique that measures the concentration of metal elements by detecting the absorption of light by ground-state metal atoms in the gaseous state. Invented by Alan Walsh in 1955, it rapidly became the standard method for trace metal analysis in environmental, clinical, agricultural, and industrial samples. Atomic absorption spectroscopy's sensitivity, selectivity, and simplicity make it indispensable for monitoring toxic metals, nutritional minerals, and elements in complex matrices. |
