| The ferrate is the oxo acid salt of Fe(VI). It has the extremely strong oxidizing power. The ferrate can be used as the oxidant of the organic synthesis for its very high selectivity; as the water treatment agents because it has the excellent purification, disinfection, decolourization functions, and the second pollution can't be caused; as electrode material of "green" battery because of its high discharged capability and discharged voltage. In a word, The use of ferrate is quite extensive.sodium hypochlorite also has very powerful oxidization capacity. Its function is quick and the effect is good, so sodium hypochlorite is used to the paper-making, spinning and weaving, waste water treatment, and so on .Studies of waste water Containing cyanogen were quite many with ferrate and sodium hypochlorite , the study is very few about waste water Containing heavy metal complex with cyanogen . On the basis of application with ferrate and sodium hypochlorite, this texts studied the best reaction conditions of all kinds of disposal methods and enlarged their applicative extentions . This has positive meanings to practical application of ferrate and sodium hypochlorite.First, waste water Containing Ag(CN)2-, Zn(CN)12- and Cu(CN)32- was disposed by composite ferrate, and its optimum response condition and disposal effect were also discussed. The results indicated that the removel rate of heavy metal complex ion with CN-, heavy metal ion and CN-all reached above 96% and that their residual quantityies are lower than the letting criteria of country after they were disposed.Second, its experimental conditions and disposal effect by using sodium hypochlorite to dispose water sample Containing Ag(CN)2-, Zn(CN)4... |
