Implementation of colorimeter sensing system for analyzing degradation of chlorine measurement / Muhammad Uwais Aiman Hamzah

This study focuses on the implementation of a colorimeter-based sensing system for analyzing the degradation of chlorine concentration in water. Chlorine is a widely used disinfectant in water treatment, but its effectiveness diminishes over time due to environmental and chemical factors. Traditional methods for monitoring chlorine levels are often labor-intensive, time-consuming, and reliant on expensive laboratory equipment, making them unsuitable for real-time applications. To address these challenges, a low-cost and reliable colorimeter sensing system was created and calibrated using known chlorine concentrations. Static experiments were conducted to monitor chlorine degradation over a 10-minute interval, with absorbance and concentration data recorded and analyzed. The collected data was used to plot degradation graphs and apply the first-order kinetic law to determine the reaction rate, providing insights into the behavior and stability of chlorine in water. The results demonstrated the effectiveness of the system in accurately measuring chlorine concentration and its degradation over time. This project offers a cost-effective and portable solution for real-time chlorine monitoring, with potential applications in water treatment facilities, environmental monitoring, and public health management. The study contributes to the advancement of water quality monitoring by providing a practical and efficient tool for understanding chlorine degradation dynamics.
