Solid waste refers to the solid, semi-solid and gaseous substances placed in containers that lose their original value at a certain time and place and are discarded. Incineration can minimize the volume and weight of solid waste. However, in the process of treating solid wastes by combustion, sulfur, chlorine and fluorine in the form of organic or inorganic substances will be converted into corrosive or harmful gaseous substances such as hydrogen chloride, hydrogen fluoride, sulfur dioxide and sulfur trioxide. The suitability of incineration of solid wastes can be evaluated by measuring the contents of sulfur, chlorine and fluorine.

In this experiment, we combust the solid waste through the oxygen bomb combustion device and absorb it with sodium hydroxide solution, and then determine the concentration of fluorine, chlorine and sulfuric acid by Ion chromatography.
