In this paper,two methods for analyzing air sulphation rate were studied and compared.One was ion chromatography and the other was barium sulfate spectrophotometry.
This work applied the new type capillary column modified by barium sulfate. It has completed the solubilty of high boiling ester in para-methyl-toluate with the method of chromatography.
The team added barium sulfate, often used to make photo paper, and calcium carbonate, something you'd find in rocks or shells, to make an even whiter, even more reflective, even cooler surface.
