The examination of their recognition abilities towards some selected oxyanions shows that the new calix[4]arene polymers are more effective receptors than their amide derivatives for dichromate anions and nitrite. It has been observed that receptor 4a is a better extractant for dichromate and nitrite anions at low pH.en10.1007/s13233-013-1152-0info:eu-repo/semantics/closedAccesscalix[4]arenepolymerextractiondichromatenitriteArticle211010911096Q2WOS:000322582600007Q2
