Shengzhou Maifan stone can dissolve more than 42 trace elements, the test results indicated that: the Maifan stone contain Fe, Zn, Ca, Cu, Mn, Cr, Mo, Zr, Ni, V, Li, Sr and other trace Elements which human body needs, the highest dissolution amount of Zn could reach 195mg /l, close to Chinese national standards for drinking natural mineral water.

The H2SiO3 solution content of boiling water by Shengzhou Maifan stone could reach 26.9～31.2 mg/l, meet The Chinese national standards for drinking natural mineral water.

Shengzhou Maifan stone contain Pb, Cd, Hg, As and other hazardous and radioactive elements U, Ra, the content is lower than the value of the abundance of elements in the crust , meet Chinese health standards for drinking water, through the toxicological tests by health and epidemic prevention station of Shanghai, prove that Shengzhou Maifan stone is non-toxic.

Shengzhou Maifan stone contains 15 rare earth elements, the total amount is 141.43ppm,the light rare earth element Ce content is up to 72.1ppm, the characteristics of stone is high contain amount Ce, good solubility.

 As result of the authorities test, Shengzhou Maifan stone has strong absorption for toxic substances which caused by environmental pollution, and its absorption performed in the form of ion exchange .

 Shengzhou Maifan stone could remove the Pb, Cd, Hg, As, and other harmful heavy metals in the water, in addition to the form of ion exchange, it performed by the silicon oxide anion groups and the positively charged ion.

Shengzhou Maifan stone could dissolve many useful elements,at the same time, it also effective absorption of harmful heavy metals, bacteria, harmful substances in the water, and so  can effectively remove the smell of chlorine in tap water.
