DETERMINATION OF CU2+ AND ZN2+ IONS IN SAMPLES USING A UV/VIS SPECTROPHOTOMETER.

The determination of metal ions such as Cu²⁺ and Zn²⁺ in various samples is crucial for environmental monitoring, industrial quality control, and biomedical applications. This study explores the quantitative analysis of Cu²⁺ and Zn²⁺ ions using UV/Vis spectrophotometry, a rapid and reliable technique based on the absorption of light by metal-ligand complexes. Optimal conditions for the detection, including wavelength selection, reagent concentration, and pH, were investigated to enhance sensitivity and accuracy. Calibration curves were constructed to determine the linearity and detection limits for each ion. The method was applied to real samples, and results were validated against standard techniques. The findings demonstrate that UV/Vis spectrophotometry provides a cost-effective and efficient approach for Cu²⁺ and Zn²⁺ determination in various matrices.

THE ROLE AND FUNCTIONS OF MODERN COMPUTER TECHNOLOGIES IN THE DIAGNOSIS OF ARTERIAL HYPERTENSION DISEASES

Arterial hypertension is a chronic disease characterized by a blood pressure of 140/90 mmHg or higher in the arteries. This pathology is widespread worldwide and negatively impacts the functioning of vital organs such as the heart, blood vessels, and kidneys. The causes of hypertension are divided into two main types: primary (essential) and secondary. Among the primary risk factors, poor nutrition, sedentary lifestyle, genetics, and stress play a significant role. In the early stages of the disease, noticeable symptoms may not be observed, but symptoms such as headaches, dizziness, and palpitations can develop. Timely diagnosis and treatment, including adopting a healthy lifestyle, are crucial in preventing severe complications of hypertension. Modern computer technologies play an important role in diagnosing and managing hypertension. They ensure early detection of the disease, improve treatment quality, and enhance the quality of life for patients. Expanding the use of these technologies in medicine could significantly reduce hypertension-related complications in the future.
