Abstract:
Objective To establish a new method for the determination of glycerin in fat emulsion.Method Glycerin was oxidized by sodium periodate to generate formaldehyde,which in turn reacted with acetylacetone to produce a derivative with ultraviolet absorption property,which was determined using ultraviolet speetrophotometer.Result This method showed high recovery (100.04％ in the linear range of content) and good precision.Conclusion This method is reliable in determining the concentration of glycerin in fat emulsion.
