Lloyd's Reagent (劳埃德氏试剂) is a specialized chemical adsorbent material historically used in pharmaceutical and analytical chemistry. Its primary component is hydrated aluminum silicate (硅酸铝水合物), processed through controlled calcination to achieve high surface area and selective adsorption properties.
This reagent derives its name from 19th-century British pharmacist Theophilus Waller Lloyd, who first documented its purification capabilities in alkaloid extraction processes. Key characteristics include:
Modern chromatography studies confirm its cation-exchange capacity (0.8-1.2 meq/g) contributes to molecular separation efficacy. While largely replaced by advanced chromatography media, it remains referenced in pharmacopeial monographs as a historical extraction agent.
