Abstract
Water is the ultimate source of life on this universe. Water is vital for the survival of humans, animals, and plants, and the issue of freshwater is becoming increasingly critical in society. With the human body composed of 64% water, contaminated water, inadequate waste disposal, and poor water management contribute to severe public health issues such as cholera, typhoid, and malaria annually. Globally, the quality and quantity of water are declining due to rapid urbanization, population growth, and industrialization. While most countries recognize the importance of freshwater, it now demands the highest priority. Chlorine, commonly used as a disinfectant, plays a significant role in maintaining hygienic conditions within public water networks. Despite concerns, at low levels in drinking water, chlorine is deemed safe and effective by health authorities. The World Health Organization sets a maximum guideline of 5 mg/l for residual chlorine in drinking water to ensure safety standards are met. Maintaining free residual chlorine in water is essential for disinfection and upholding safety standards. In this case study, we aim to determine the free chlorine residual content in the water of Jalandhar city, Punjab, India. In this study, we employed a colorimetric method coupled with a calibration curve to accurately determine the free residual chlorine content in a given water sample. The calibration curve was constructed using standard solutions of known chlorine concentrations, and absorbance measurements were obtained using a colorimeter across a range of wavelengths. Subsequently, the absorbance values of the water sample were compared to the calibration curve to interpolate the corresponding free residual chlorine concentration. The experiment demonstrated a reliable and precise method for assessing chlorine levels in water, essential for ensuring its suitability for various applications, including drinking water treatment, swimming pools, and wastewater treatment. This approach offers a cost-effective and efficient means of monitoring chlorine levels, contributing to the maintenance of water quality and public health. The findings provide valuable insights into the quality of drinking water in Jalandhar city and contribute to efforts aimed at ensuring safe water to the residents. By conducting colorimetric analysis on water to assess the efficacy of chlorination at Jalandhar city and contribute to the understanding of water quality.
