This standard describes barium sulfate Nephilometry for the determination of sulfate content in lithium carbonic acid, lithium hydroxide monohydrate and lithium chloride. Absorbance measurement at 420 nm in a spectrophotometer to calculate the sulfate content by reacting with barium ions in a muriatic acid medium to produce insoluble barium sulfate settling. The standard applies to assays ranging from 0.050% to 0.800% (mass fraction) and provides accurate analytical methods to ensure quality control of chemicals.
