Optical properties of daily used water in Kathmandu valley

Abstract

Abstract This article comprehensively examines the characteristics of water samples sourced from diverse locations in the Kathmandu Valley, encompassing density, transmittance, absorption coefficient, mass attenuation coefficient, and molecular cross-sectional area (MCA), across varying temperatures. Density variations, within a temperature range of 8 °C to 48 °C, are reported, spanning from 1.17725 to 1.0015 g/cm3. Transmittance increases with wavelength and exhibits temperature-related variations due to differing impurities among sources. The relationship between transmittance and temperature lacks a distinct pattern, influenced by unique source impurities and temperature effects. Moreover, the MCA estimates particles to be approximately 10−24cm2. Additionally, the mass attenuation coefficient consistently decreases with wavelength across all samples. These findings provide a comprehensive insight into the intricate interplay between water properties, impurities, temperature, and radiation interactions in various water sources.
