3, vacuumize its moisture evaporate to dryness at 80-90 DEG C of temperature, be placed in Muffle furnace, under the protection of nitrogen, at being warming up to 800-900 DEG C, obtain modified aluminium powder adsorbent;
4, modified aluminium powder adsorbent and active carbon according to 1:5 mix enter into mass concentration be 5% sodium hydroxide solution soak 12-24h;
5, above-mentioned mixed liquor is filtered, and dry in the Muffle furnace of 100-105 DEG C, the mixed-powder of having dried is placed in dyeing waste water, then by spectrophotometer, methylene blue in waste is detected.
Application process of the present invention is:
1, aluminium foil powder airslide disintegrating mill is ground into aluminium powder, and utilizes standard screen screening to be 200-300 order;
2, the aluminium powder after screening is placed into 1-2h in 30% ammonium peroxydisulfate, and adds 3%-5% urea wherein, at 60-70 DEG C of temperature, stir 2-3h heating, then add 10-50ppm neopelex continuation stirring, 1-2h wherein;
3, vacuumize its moisture evaporate to dryness at 80-90 DEG C of temperature, be placed in Muffle furnace, under the protection of nitrogen, at being warming up to 800-900 DEG C, obtain modified aluminium powder adsorbent;
4, modified aluminium powder adsorbent and active carbon according to 1:5 mix enter into mass concentration be 5% sodium hydroxide solution soak 12-24h;
5, above-mentioned mixed liquor is filtered, and dry in the Muffle furnace of 100-105 DEG C, the mixed-powder of having dried is placed in dyeing waste water, then by spectrophotometer, methylene blue in waste is detected.
The significant advantage that the present invention has is:
(1)with aluminium foil powder for raw material, adopt two ammonium sulfate chemical modifications, modified aluminium powder short texture, define the hole loose structure with certain adsorptivity;
(2)utilize modified aluminium powder treatment of dyeing and printing, have treatment effeciency high, not easily cause secondary pollution and the easy advantage such as control.
