UV-visible (UV-Vis) spectroscopy is a powerful instrument for investigation and quantitative detection of qualitative pollutants in water. UV-Vis spectrophotometry is an analytical method using the concept of transmission of light in UV and Visible wavenumber. Generally, compounds can be identified using UV-Vis Spectrophotometry, based on the concept of light absorption, specifically for compounds with a chromophore group and an auxochrome group. Although the utilization of UV-Vis spectrum analysis has been well-documented, no information regarding detailed step-by-step measurement for examining detailed quantitative analysis, particularly in determining the concentration of an analyte in an aqueous solution sample. Here, this study explores the idea and application of UV-Vis technology in water quality detection, the concentration of the sample in an aqueous solution. To support the analysis, we also added practical examples for understanding organic decomposition. This paper is intended to be useful for researchers and students in understanding UV-Vis spectrophotometry when analyzing chemical composition during chemical decomposition, photocatalysis, phytoremediation, and adsorption analysis.

The study provides a detailed guide for quantitative analysis using UV-Vis spectrophotometry, particularly for determining sample concentrations in aqueous solutions during processes like chemical decomposition, photocatalysis, phytoremediation, and adsorption.It demonstrates the importance of standard solutions, calibration curves, and accurate absorbance measurements for determining pollutant concentrations.The research underscores the utility of UV-Vis spectroscopy as a valuable tool for understanding and assessing water quality and chemical processes.

Penelitian lebih lanjut perlu dilakukan untuk mengembangkan spektrofotometer UV-Vis portabel dengan biaya rendah yang dapat digunakan langsung di lapangan untuk pemantauan kualitas air secara real-time, terutama di daerah terpencil atau berkembang. Pengembangan metode analisis baru yang menggabungkan spektrofotometri UV-Vis dengan teknik sensorik lainnya, seperti sensor elektrokimia atau biosensor, dapat meningkatkan sensitivitas dan selektivitas deteksi berbagai polutan dalam sampel air yang kompleks. Studi komparatif yang lebih mendalam perlu dilakukan untuk membandingkan efektivitas dan efisiensi berbagai metode preparasi sampel dan teknik kalibrasi dalam analisis spektrofotometri UV-Vis, dengan mempertimbangkan matriks sampel yang berbeda dan rentang konsentrasi analit yang bervariasi. Penelitian selanjutnya dapat difokuskan pada pengembangan model prediktif yang kuat menggunakan teknik kemometrik untuk memperkirakan kualitas air dan konsentrasi polutan berdasarkan data spektrum UV-Vis, sehingga dapat memberikan informasi yang cepat dan akurat mengenai kondisi lingkungan perairan.
