GB/T 11064.9-2023 《Methods for chemical analysis of lithium carbonate, lithium hydroxide monohydrate and lithium chloride—Part 9: Determination of sulfate content—Barium sulfate turbidity method》 Related products

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.
