At pH 10 and 13:00, 2084cm bands began to disappear,<a href="http://www.toryburchflipflops.com" target="_blank" class="postlink">tory burch flip flops</a>, Prussian blue started to decompose. At high pH, the appearance of other bands may be due to Fe: O ・ nHO due to the different forms. Sediment under different pH x-ray diffraction patterns of a comparison is shown in Figure 8.

Conclusion The environmental requirements of all cyanide solution should be reduced to a prescribed level, not the solid cyanide. Therefore, the method must be optimized to form ferrous sulfate precipitate of Prussian blue, rather than generate soluble ferrous cyanide complex. And FeSO by Prussian blue reaction of cyanide in the best conditions to remove the following; pH5 .5 to 6.5FeICN than 0.5 drum into the oxygen or ammonia are harmful to the removal of cyanide oxidation result t of oxygen in the solution generated in the ferrous cyanide and iron cyanide | ammonia solution led to the formation of ferrous cyanide. Ferrous cyanide ion is unstable in acidic solution, not the formation of five-iron cyanide complex ion Fe (CN) ・ H. O, is the rapid oxidation of iron cyanide Fe (CN): one. In the pH value is less than 4 of these reactions occur. CN in excess of a reaction of FeSO and sediment generated mainly insoluble Prussian blue, FeEFe (CN)..). Prussian blue precipitate in the range pH1 ~ 7 is stable, but in alkaline solution is unstable, decomposing rapidly in alkaline solution into Fe (CN) l entered the solution. At pH greater than 7, it produces a variety of insoluble iron oxides Fe2O. ・ NH2O (n = 1 ~ 3).
