china purpose of using titanium dioxide in soil ph

2. The preparation of the lining powder: The above-mentioned final immersion liquid 1000 ml in a 2000 ml beaker, heated to 98 ° C, and then added 4 g of ammonium persulfate with a magnetic stirrer stirring 0. 5h, after the oxidation of the solution, adding polyacrylamide 02%。 The solution, the volume of the solution is 0.02%. After lh filtration, the obtained filtrate is subjected to sulfurization and impurity removal, and zinc powder is substituted to obtain a zinc sulfate ammonia refining complex liquid. 122. 9g of antimony sulfide (without water) and 21. 7g of sodium sulfide (without water) are mixed and dissolved in distilled water to obtain a metathesis reaction solution, and a nonionic surfactant 0P-10 (for nonylphenol and epoxy) is added to the solution. The condensate of acetamidine) 0. 2g, the reaction temperature is 40 ° C, the stirring speed is 15m / s, stir well for 40min, then slowly added to 1000ml zinc sulfate ammonia refining complex, continue to stir for 30min and then add quality The fractionation is 30% 3⁄40 2 of desulfurization bleaching, and after bleaching, the nZnS-BaS0 4 crystal filter cake is separated by filtration.

 At present, Lide powder is mainly produced in China. Most of the domestic Lide powder production is still using traditional methods. The main raw materials are zinc oxide, sulfuric acid and barium sulfide (barite and coal are produced by high temperature reduction). Zinc 45% ~ 70%. The traditional method for producing the Liede powder process is to use zinc bakelite containing more than 45% zinc as a raw material to be leached with sulfuric acid to obtain a crude zinc sulfate solution, and then to remove iron by potassium permanganate, and then replace the heavy metal with zinc powder and filter to obtain zinc sulfate. The refined liquid is further subjected to metathesis reaction, pressure filtration, calcination, rinsing, drying, and pulverization with strontium sulfide to obtain a series of different types of lindose powder containing zinc sulfide of 30% or more. The whole process is carried out in an acidic (ra<7) environment, which consumes a large amount of sulfuric acid. The sulfuric acid has strong corrosiveness and requires high production equipment. The final discharged slag is acidic slag, which brings new pollution to the environment. High requirements, high production costs, and poor quality of the products obtained.
