摘要
nanoadsorbent based on hydrated oxides of aluminium, iron and manganese removal from water arsenitanů and arseničnanů contains amorphous hydrated oxides respectively as ternary aluminium, iron,manganese in the molar ratio 0.5: 4.5: 1.5 to 3: 4.5: 1,5. the concentration of oxides of at nanoadsorbentu is up to 60% hmotn., a particle size of 10 to 100 nm, the specific surface area of 50 to 100 m2 / g.production method nanoadsorbentu lies in the fact that the solutions of salts of aluminium, iron and manganese are mixed in the molar ratio of al: fe: mn = 0.5: 4.5: 1.5 to 3: 4.5: 1.5, the addition of naoh to adjust the ph to 9.5 and 10.the mixture is allowed to age for a period of 10 to 14 hours, the solid phase is separated and dried at a temperature of 200 to 250 degrees celsius for a period of 11 to 14 hours. nanoadsorbent may be mixed with sodium na2sio3 at 25 to 35% by weight.and granulovat.
