Pure water we usually mean is pure water, does not contain any harmful substances and bacteria, such as organic pollutants, inorganic salts, any additives and various impurities. Its advantage is that it can effectively and safely replenish water to the human body. Strong solubility, have you ever thought that pure water is conductive ? The following small series helps everyone solve this problem.
The metal element index specifies the content of lead, arsenic and copper in the standard. The requirements for lead and arsenic shall not exceed 0.1 mg/L, which are mainly derived from the environment affected by human activities, including soil and river pollution. Lead and arsenic are toxic and harmful elements. Lead can enter the human body through the respiratory tract or digestive tract and accumulate in the human body. When the lead content in the blood is 0.6-0.8 mg/L, the internal organs will be damaged, and the arsenic compound will cause poisoning. The content of them should be as small as possible, and copper should not exceed 1.0 mg/L in the standard. Although copper is not a harmful element, it is not a good material. For pure water, it is a measure of its purity. one. Is pure water conductive ? Conductivity is a characteristic indicator of pure water, reflecting the purity of pure water and the control of the production process. Since drinking water does not undergo deionization purification, this indicator is not considered. For pure water, "pure" is its most basic requirement. Metal elements and microorganisms are too high, which will lead to high conductivity. Therefore, the smaller the conductivity, the purer the water.
Potassium permanganate consumption refers to the number of milligrams of oxygen consumed by a reducing substance in 1L of water when it is oxidized by potassium permanganate under certain conditions. It mainly investigates the content of organic matter, especially chloride, in water. GB17323-1998 "Bottled drinking pure water" stipulates that the consumption of potassium permanganate (in O2) in drinking pure water shall not exceed 1.0 mg/L. If the consumption of potassium permanganate is too high, there may be excessive microbes in the water. It may also be that some manufacturers increase the amount of disinfectant ClO2 to prevent microbial exceeding the standard, thus producing some new organic halogenated substances. In this case, generally Free chlorine will also exceed the standard. In the process of pure water, trace elements such as Cu, Fe, Zn, F or macro elements S, P, Ca, Mg, Na, and K are also removed, and the higher the pure water rate, the various benefits to the human body. The greater the loss of health ingredients. Therefore, there are advantages and disadvantages to replacing drinking water with pure water. If it is the "pure water" that we talk about in our daily life, that is, the general drinking water, it is electrically conductive. It contains free moving ions and other impurities, so it is conductive. There is also a kind of so-called "pure water", which is not electrically conductive. Chemically speaking, water itself is a very weak electrolyte, which is very weakly ionized, so pure water without impurities, freely moving ion concentration At the negative 7th order of 10, it can be ignored, that is, basically no.
The above is the information about the pure water conductivity introduced by Xiaobian for everyone, I hope to help everyone, this article is for your reference only!
