Determination of Concentration of the Byproducts in Desulphurization Liquid

摘要

Hydrogen sulfide is a kind of toxic and harmful gas. If discharging it directly or discharging it after it is burnt into sulfur dioxide, it may cause terrible pollution to atmosphere. Wet Desulphurization is a common method, but there is minor products in the mother liquor of desulphurization. This paper adopts the method of simulating mother liquor of desulphurization, by adding into minor products Na_2S_2O_3 and NaSCN to determine the highest concentration of the mother liquor.
