Background
Strontium is a trace element required by human body, and has effects of regulating bone tissue structure, improving bone strength, and promoting bone cell physiological activity. In addition, strontium has effects of preventing cardiovascular diseases, preventing dental caries, resisting oxidation, resisting aging, and caring skin. The supplement of trace elements can be realized by edible health care and medicaments. However, this approach tends to have hysteresis and is difficult to achieve prophylactic efficacy. In addition, the relevant formulations are also generally expensive.
Water is an essential nutrient and also a carrier for other nutrients, particularly trace minerals. With the improvement of the national standard of living, the demand of consumers for drinking water gradually changes from clean water to healthy water. The water purification technology most used in the domestic water purification industry is reverse osmosis technology, which can remove substantially all metal ions in water. But due to the reverse osmosis membrane pair CO2The water is sour due to no removal capability, and the health of human bodies is influenced after long-term drinking.
Most of the existing drinking water mineralizers adopt natural minerals, however, the natural minerals are complex in components, and heavy metals and radioactive substances are often dissolved out while beneficial elements are dissolved out. In addition, with the increase of the soaking time, the dissolution concentration is too high, the pH value of the drinking water is too high, and the long-term drinking can affect the human health. The research also adopts the mineralizer which is artificially compounded to supplement beneficial elements in drinking water, but the problem that the concentration of each element in the drinking water exceeds the drinking water standard after the drinking water is soaked for a long time cannot be solved.
