FIELD: chemistry. ^ SUBSTANCE: method of aluminium porous membranes production involves aluminium foil polishing, anodic oxidation, pore bottom opening at temperature 40-50°C in mixed concentrated fluorohydrogen, nitric and acetic acids in ratio as follows, volume percents fluorohydrogen acid : nitric acid : acetic acid as (2.5-3.5):(1.5-2.5):(4.5-5.5) and pore canal cleanup. ^ EFFECT: uniform pore opening without destructing work structure bases. ^ 2 cl, 4 dwg |
