WebK-5543 uses of Ferric Thiocyanate Method, which method consists to ammonium thiocyanate furthermore iron-containing iron in acid solution. H peroxide oxidizes iron iron to the ferrate state, resulting in the formation of a red thiocyanate complex. Chlorine will not interfere with these method. Ferric iron and peracetic acid will interfere. Web15 nov. 2015 · In the pH at 1.0 the peak current of the complex was linearly dependent upon the concentration of Th(IV) within the range of 2.0 × 10−9–2.2 × 10−8 M, with the limit of detection 0.2 nM, the accumulation time, and the accumulation potential were 200 s and −0.6 V, respectively.

WebComplex A does not react with concentrated H2SO4, whereas complexes B and C lose 6.75% and 13.5% of their original weight, ... is obtained. The solution (E) on treatment with thiocyanate ion gives blood red compound (H). Identify (A) to (H). ... Addition of ammonium molybdate solution to conc. HNO3 solution of (D) gives a yellow ppt of (E). WebIn the case of Fe(III), thiocyanate is bonded through nitrogen [25]. Sultan and Bishop reported that even at 1:5000 ratio of Fe(III) to thiocyanate only 1:1 complex is formed in an acidic medium [26]. Hence, a large excess of thiocyanate was maintained to ensure the complete conversion of metal ion to [M(SCN) 4] 2-complex.
