Abstract
This study demonstrated how a dye solution’s per cent colour degradation (η) may be calculated using the total dissolved solids (TDS) meter. As test solutions, varied concentrations of the brilliant blue solutions were utilised. We compared the results of TDS meter readings for per cent degradation with those of standard spectrometer measurements. The results of our measurements agree with those of a spectrometer. Therefore, TDS meters can be used as an option to measure colour degradation, particularly in laboratories lacking a spectrometer, considering that the price of a TDS meter is much more affordable than that of a spectrometer. A TDS meter with high accuracy must be used for scientific purposes demanding highly precise measurement findings.
