WebDec 1, 2024 · Finally, HCNO reacts with HO – to produce CNO – (reaction 8). As an alternate pathway, these formamide radicals could readily react with the double bonds of the GO, adding the amide moiety to its structure (reaction 6), and forming an amide-functionalized graphene oxide (A-GO), as depicted in Fig. 2. WebWith Caro’s acid, the conversion of cyanide to cyanate is complete in a few minutes, according to the following equation: CN - + H 2 SO 2 → CNO - + H 2 SO 4 (pH 10) The addition of excess Caro’s acid will hydrolize the cyanate to carbonate and nitrogen in the same step: 2OH - + 2CNO - + 3SO 52- → 2CO 32- + N 2 + 3SO 42- + H 2 O
