Abstract

This work aims to measure the different parameters of Dhunge Dhara water (DDW) such as absorbance, transmittance, mass attenuation coefficient (MAC), and molecular cross section (MCS) and experimentally compare the obtained values with those of pure water (PW) at various temperatures (5 °C to 90 °C) using a theremino spectrometer. Observation shows that the parameters vary with temperature and wavelength. The transmittance of DDW ranges from 18% to 85% and absorbance of the same ranges from 0.09 Au to 0.7 Au. Meanwhile, the transmittance of PW ranges from 40% to 98% and the absorbance of the same ranges from 0.09 Au to 0.39 Au. The MAC of PW ranges from 0.02 cmg to 0.6 cmg, and that for DDW ranges from 0.2 cmg to 1.1 cmg at 30 °C. The MCS of PW ranges from 0.1 × 10cm to 2.7 × 10cm, and that of DDW ranges from 0.9 × 10cm to 5.5 × 10cm at 30 °C. In conclusion, DDW has an extremely high amount of impurities and total dissolved solids and is recommended to be filtered prior to use (drinking and cooking).

温度对Dhunge Dhara饮用水光学性质、衰减系数和总分子截面的影响

本工作旨在测量Dhunge Dhara水(DDW)的吸光度、透过率、质量衰减系数(MAC)和分子截面(MCS)等不同参数，并利用热谱仪实验比较不同温度(5℃~ 90℃)下Dhunge Dhara水(PW)的值。观测表明，这些参数随温度和波长的变化而变化。DDW的透过率为18% ~ 85%，吸光度为0.09 ~ 0.7 Au。同时，PW的透过率在40% ~ 98%之间，吸光度在0.09 ~ 0.39 Au之间。30℃时，PW的MAC值为0.02 ~ 0.6 cmg, DDW的MAC值为0.2 ~ 1.1 cmg。30℃时，PW的MCS范围为0.1 × 10cm ~ 2.7 × 10cm, DDW的MCS范围为0.9 × 10cm ~ 5.5 × 10cm。总之，DDW含有极高的杂质和总溶解固体，建议在使用(饮用和烹饪)之前进行过滤。
