Abstract: Ultraviolet-visible (UV-vis) spectroscopy is a spectral measurement technique that relies on Lambert-Beer's law. Due to its user-friendly nature, rapid analytical capabilities, broad applicability, and non-destructive properties, it has gained significant prominence across various scientific disciplines. In the realm of environmental science, UV-vis spectroscopy can be employed for effectively detecting water quality by determining the concentration of heavy metals and related chemicals in water sources. Within the field of clinical medicine, UV-vis spectroscopy plays an indispensable role in disease diagnosis and patient health monitoring. Agriculture and plantation industries greatly benefit from UV-vis spectroscopy due to its capability in facilitating precise analysis of soil and plant nutrients. The field of materials science heavily relies on ultraviolet-visible spectroscopy for the examination of optical properties pertaining to various materials. Moreover, UV-vis spectroscopy finds extensive application in organic chemistry for compound identification and purity evaluation. This research aims to provide a comprehensive overview of multiple applications of UV-vis spectroscopy while exploring its potential synergies with specific technologies across different fields.
