Activated carbon adsorption uses the solid surface of activated carbon to adsorb one or more substances in water to achieve the purpose of purifying water. The adsorption capacity of activated carbon is related to the pore size and structure of activated carbon. The smaller the particles, the faster the pore diffusion rate. The stronger the adsorption capacity of activated carbon is; the natural mineral water purification filter material is modified by a hydrous skeleton aluminosilicate mineral composed of silicon oxide and aluminum oxide tetrahedrons, which has a unique crystal structure and crystal chemical properties. The specific surface area reaches 500-1000m2/g), and the volume of holes and channels accounts for more than 50% of the volume of natural mineral crystals.
