Nano yellow tungsten oxide may be applied for nano-ceramic color master, which not only plays a role in dyeing, but also has the effect of enhancing the toughness of the ceramic. Certainly, yellow tungsten oxide may also be used for sewage treatment. And it works, for oily wastewater.
Yellow tungsten oxide was subjected to oil water separation experiment and emulsion separation experiment. Oil water separation experiment: First, n-hexane and water were dyed with Sudan Tris and Methyl Blue, and an oil water mixture of n-hexane and water was prepared at a volume ratio of 1:1. Then, stainless steel net coated with yellow tungsten oxide was clamped between the two glass tubes with a clip, and the apparatus was fixed on the iron frame table, and then the stainless steel net was wetted with deionized water. Finally, the obtained oil water mixture is slowly poured into a previously prepared oil water separation device. Emulsion separation experiment: First, a volume ratio of 100:1 of water and n-hexane was stirred for 3h to obtain an oil-in-water emulsion. Then, the obtained emulsion was slowly poured into the above oil water separation device.
