Problems solved by technology

Moreover, zirconium hydroxide is non-toxic and harmless, and can be used to prepare hemodialysis materials and regulate the content of phosphorus in the blood. Now it is mainly to prepare a zirconium hydroxide material with a suitable particle size and large adsorption capacity, while the existing zirconium hydroxide material Insufficient stability, the particle pores used for adsorption are also unevenly distributed, and the amount of particle pores formed is small, resulting in low adsorption capacity when purifying water and performing hemodialysis

Abstract

The invention discloses a micron-scale zirconium hydroxide, with a pore size of 1.8-2.8 nm; a pore volume of 0.18-0.28 cm3 / g; ~680m2 / g, the zirconium hydroxide has a hollow structure. The invention also discloses the preparation method of the zirconium hydroxide, its application in purified water and its adsorption in hemodialysis. The micron scale of the present invention can adsorb phosphate, sulfate and fluoride ions in water, and can also adsorb phosphate in hemodialysis.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to the field of purification technology, in particular to a micron-sized zirconium hydroxide, its preparation method and application. Background technique [0002] Sulfate, phosphate and fluoride ions are common anions in chemical production. Their existence will bring great harm to production and the environment, and pollute water quality. The phosphate ion content in human blood is too high, which seriously affects human health. At present, the main methods used in industry to remove sulfate, phosphate and fluoride ions in water include chemical precipitation, electrocoagulation, biological method and adsorption method. However, the purification efficiency of the chemical precipitation method and the biological method is relatively low, and the electrocoagulation method will increase the cost and consume a lot of energy. The adsorption method not only has high efficiency, but also the...
