Activated alumina desiccant activated alumina _ _ Heilongjiang haohai water

 γ-alumina is aluminum hydroxide at a low temperature of 140-150 ℃ dehydration, also known industrially activated alumina, alumina gel. Its structure is closely packed oxygen ions is approximately centered cubic, Al3 + irregularly distributed surrounded by oxygen ions in octahedral and tetrahedral voids being. γ-alumina is insoluble in water, soluble in acid or alkali solution, it was heated to 1200 ℃ on all converted to α-alumina excessive fluoride in well water has a great harm to the human body, according to the national drink of life water health standards, the fluorine-containing well water should not exceed 1.0 mg / L, if long-term drinking water activity fluorinated alumina process exceeded easily lead to fluorosis activated alumina, fluorosis is a chronic systemic disease, excess fluorine After entering the body, it will form dental fluorosis and skeletal fluorosis, resulting in teeth yellow, brown or dark brown, gradually shedding the defect; the emergence of low back pain, stiff joints, skeletal deformities, leg bent, bent, and even paralysis and other symptoms, elderly fracture easily, affecting the normal development of the child intelligence. In China, a large part of the region, the fluorine content in well water is more than the national standard, severe regional or even ten times the relevant provisions. How should we deal with that excess fluorine wells it? Activated alumina desiccant activated alumina _ _ Heilongjiang haohai water provided by Gongyi City Water Treatment Materials Co., Ltd. Hao Hai.
