Method for obtaining a photocatalyst based on titanium dioxide doped with iron (III) and method for producing a filter that contains the photocatalyst based on titanium dioxide doped with iron (III), preferably for 3D printers

摘要

the object of the application is to receive fotokatalizatora way based on titanium dioxide doped with iron (iii), especially for 3d printers, in which a suspension of titanium dioxide at a concentration of at least 10 g / dm3, advantageously in the form of anatase and / or rutile, in water so, to which is then added with inorganic salt of iron (ii)preferably in the form of siedmiowodnego sulphate (vi) iron (ii), in quantities of from 1% to 5% by weight. iron in relation to the weight of titanium dioxide, after which the mixture is subjected to the action of ultrasonic so obtained in an ultrasonic bath in time from 5 min to 2 h, and then odwirowuje precipitated and washed with distilled water and ethanol, then dried at 50 - 70 oc for at least eight hours.and then in the subsequent stages of put and wyprau017ca at 500 - 600u00b0c in air flow for at least 2 h, after which favourably again put. the object of the application is also fotokatalityczny filter based on titanium dioxide doped with iron (iii), especially for 3d printers.
