| Abstract: | The splitting decomposition of light oil goes as follows:first,generate HCN through the electrode reaction adopting the oil code as a vehicle with the light oil and NH 3 in proportion ; then, absorb NaOH solution to generate NaCN, which contains S. The old method of analyzing the content of NaCN employs the standard AgNo 3 titration solution to test the content.However,the generation of Ag 2S sediment aftre the reaction of S 2- and AgNO 3 inflenences the test. |
