- Abstract:
- The metal elements in water supply systems have complex speciation and special chemical and biological characteristics, which is an important control index to ensure the safety and stability of drinking water. The speciation and correlation of 16 metal elements in a water supply network of N city in southern China were determined by inductively coupled plasma mass spectrometry (ICP-MS).The increase in total aluminum in the water supply network was mainly caused by the increase in suspended aluminum. The increase in total iron, total manganese and total zinc was mainly caused by the increase in suspended and soluble iron, manganese and zinc, and the change in total barium was attributed to the increase in soluble barium. The contents of suspended aluminum, iron and manganese in water of the pipe network had great spatial differences. Pearson correlation analysis showed that there were strong positive correlations between suspended metals, such as aluminum and manganese, aluminum and barium, manganese and copper and manganese and barium (p<0.01), and moderate positive correlations between suspended metals such as aluminum and titanium, aluminum and copper, titanium and iron, copper and zinc and copper and barium (p<0.01).
