摘要: In this work, a new chromogenic calix(4) arene was functionalized onto self assembled monolayer (SAM) of cysteamine for cadmium ions detection and tested by using SPR measurement. The functionalization modified sensor is based on the oxidation calixarene-SAM alcohol group to quinone. Four interfering were used Cu2+, Co2+, Mg2+ Ca2+. pH in which sensitivity higher optimized made basic solution. Detection limit reached Cd2+ lower than 10(-11) M with dynamic response time about 16 s when changing from 10(-6) 10(-5) M.
