Abstract:
0.999 5), RSD were no more than 3.0%. The recovery rates were 98.0%-102.0%. There was no significant difference between the results of this method and EDTA-Na2 titration. Conclusion The method is rapid, accurate, simple, little disturbance and is acceptable in determination of total hardness in drinking water.
