The other said, experiments show that the presence of heavy metals in tap water, it is necessary to buy a water purifier can remove heavy metals. Similar water purification demonstration effect, but also show the number of stores in the Castle Lane.

   In fact, the Shanghai World Expo drinking water core technology inventor, vice chairman of China Film Industry Association Chen Lianggang told reporters, tap water calcium and magnesium ions is a iron bar electrolyte, anode electrolysis apparatus into the water, iron electrolytic iron hydroxide is formed after (gray), a divalent iron ion (green), ferric oxide (red-brown), tri-iron tetroxide (black); and pure water free of calcium and magnesium ions conductive, electrolysis does not occur reactions, it does not change color of pure water. If pure water with mineral water, mineralized water or put a little salt to do the experiment, the water will still be discolored.
