应用
Determining sulfate radical by barium chloride titration with rhodizonic acid disodium salt test paper as indicator has been established. Staining of thin sections for quick identification of quartz, potash feldspar and plagioclase is usually done with sodium hexanitrocobaltate (III) and rhodizonic acid disodium salt. N-allyl-N?-(sodium p-phenyl-sulfonate)thiourea is used for eliminating the interference of Ag +?Au 3+?Hg 2+in the identification of Sr 2+ using Rhodizonic acid disodium salt. 备注
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents. 基本信息 MDL
