Abstract: In this study, the practical aspects of determining Cu(II), Zn(II), and Ni(II) ions using various analytical techniques are investigated. The quantification of these metal ions is crucial for scientific and medical research, as well as for environmental monitoring. In recent years, numerous methods have been developed that ensure high accuracy, speed, and sensitivity in their determination. The paper reviews different analytical methods for determining Cu(II), Zn(II), and Ni(II) ions, emphasizing spectrophotometric and associated physicochemical techniques. The spectrophotometric technique stands out among other analytical methods due to its high precision, rapid operation, and low reagent consumption, making it an effective tool in environmental and biomedical research. Special spectrophotometric reagents, their application conditions, measurement procedures, and possible sources of error are examined in detail. Apart from spectrophotometric analysis, other instrumental techniques like atomic absorption spectroscopy, potentiometric titration, ion-selective electrode measurements, and X-ray fluorescence spectroscopy are systematically reviewed regarding their advantages and drawbacks. These methods enable the detection of trace concentrations of Cu(II), Zn(II), and Ni(II) ions, allowing for a deeper understanding of their biological activity and physiological effects. Overall, the study focuses on the practical applications of analytical chemistry and highlights its significance in medicine, environmental science, and biological research.
