A polycationic organohalloysite (H‐polyQ22) prepared by the sequential grafting of methylamine and 1,4‐butanediol diglycidyl ether in the interlayer space of (3‐aminopropyl)trimethoxysilane grafted halloysite is herein employed as a carbon paste electrode (CPE) modifier for the electrochemical determination of mangiferin, a bioactive molecule. When H‐polyQ22 was used as CPE modifier, the cyclic voltammetric...
A glassy carbon electrode (GCE) coated with a thin film of organoattapulgite was used for the voltammetric detection and quantification of mangiferin (MG), a bioactive xanthone with several therapeutic properties. The used modified attapulgite was prepared by surface grafting of [3‐(2‐aminoethylamino)propyl]trimethoxysilane. The grafted clay was characterised by SEM, CHN elemental analysis, FTIR spectroscopy...
