摘要: Abstract It is a challenging task to develop simple method detect the biologically important anion H2PO4− in aqueous solution. Herein, highly sensitive colorimetric sensor was designed this paper. based on self-assembly technique of p-Sulfonatocalix[6]arene functionalized Ag NPs clusters which can enhance sensitivity and selectivity detection. This also realize real-time quantitative detection for with limit 10−7 M.
