Green synthesis of cobalt and iron incorporated citric acid/ β ‐cyclodextrin composites: Efficient H 2 O 2 scavengers

Sonochemical procedure was used to synthesize Co/β-cyclodextrin complex. For the first time, Fe/β-cyclodextrin complex also synthesized in alkaline media. Moreover, β-cyclodextrin modified by citric acid (CA) and reacted with metal salts under ultrasonic irradiation. The prepared catalysts were characterized using EDX, UV–vis FTIR analytical techniques. highest incorporation of into observed cross linked β-CD. catalase like activity (peroxide scavenging) Co/β-CD Fe/β-CD complexes composites evaluated UV–visible spectrophotometer their superoxide scavenging capacity measured pyrogallol method. Co3/CA-β-CD showed best mimetic (93.2%) even comparison enzyme extracted from potato. Therefore, cobalt acid/β-CD are promising candidates for H2O2 scavenging. By contrast Fe3/CA-βCD had stronger capability eliminate anion radicals.
