| Abstract: |
| In this paper, different types of demulsification experiments have been carried out for emulsified sulfur-containing sewage, and the iron content of the samples after demulsification has been determined to determine the demulsification method suitable for sulfur-containing sewage. By controlling a single variable to study the influencing factors in the determination of iron content in emulsified sulfur-containing wastewater, it is determined that when the sample volume is 50mL, the addition amount of n-butanol is 2.5mL, the addition amount of hydrochloric acid is 5 drops, and the pH of the sample is adjusted to 4.5 after digestion Experimental program. It is verified by experiments that the method is suitable for the determination of iron content in emulsified sulfur-containing sewage. |
