| Abstract: | Water hardness was determined by complex titration and eriochrome black T （EBT） selves as the indicator. The main factors affecting the accuracy of the determination of water hardness include the pH of samples,amount of indicator and Mg-Y,amount of masking agent,was investigated systemically with a standard water sample. The method was applied to determine the hardness in water samples from different areas in Zhaoqing city. Results showed that the hardness in water from the biggest down to the smallest was sewage, Xijiang River, tap water and natural water, respectively. |
