Thus, the total dissolved solids test qualitatively measures the number of dissolved ions but does not tell us the nature or ion relationships. In addition, the test does not provide us insight into the specific water quality issues, such as Elevated Hardness (mineral content in water)...
By using in particular an aqueous ethanolic imidazole buffer with a pH value of 6.75, conditions can be set up in such a way that the o-CPC has an identical molar sensitivity with respect to Ca and Mg. The total water hardness of aqueous samples can thus be easily determined. ...
Sodium adsorption ratio, EC, magnesium hazard ratio, sodium percentage, and total hardness indices were used to evaluate the quality of GWL. These indices indicated poor groundwater quality in the aquifer. This study shows that the CNNE-LOST-GPRE is a reliable model for predicting complex ...
