Abstract
The effect of the method of aluminum nanopowder production on the aluminum products with water reaction is described. It has been established that the interaction of aluminum nanopowder prepared by the electric wire explosion, the phase composition of the reaction products mainly consists of boehmite (AlOOH) and has a fibrous structure. Therefore, that boehmite (AlOOH) can be used for modification of polymer membranes. The modified membranes can be used as water treatment from the impurity of formed true solutions according to adsorptive mechanism, and from colloidal nanometer and micron particles according to the mechanism of mechanical separation of particles depending on sizes.
Highlights
Modern methods of producing nanofibrous aluminum oxyhydroxide (AlOOH) sufficiently diverse due to their use in the synthesis of various precursors based on aluminum, such as salts or in the form of metal powders [1,2,3,4,5]
The basis of these methods is the chemical synthesis of aluminum oxyhydroxide
The first method is basing on the interaction of water and nanodispersed aluminum particles generated by electric wire explosion in an argon environment
Summary
Modern methods of producing nanofibrous aluminum oxyhydroxide (AlOOH) sufficiently diverse due to their use in the synthesis of various precursors based on aluminum, such as salts or in the form of metal powders [1,2,3,4,5]. The salts used as starting chlorides, nitrates and sulfates of aluminum With this method of producing aluminum oxyhydroxide, its composition and properties depend on the pH and temperature of the reaction medium. One way to obtain aluminum oxyhydroxide with desired properties is aluminogels hydrothermal treatment The advantages of this method are the possibility of choosing the parameters (t, P, τ), providing the properties of good reproducibility and high quality product. A disadvantage of this method is the necessity of using high temperature and pressure, which affects the final product cost
