Sensors for detecting and distinguishing metals in a sample comprise phenol group-containing azo dyes, the phenol group having one hydroxy involved in reversible metal ion binding and a second hydroxy alkylated to an optically transparent substrate. The sensors have utility for detecting chromium, calcium, magnesium, copper, mercury, nickel, zinc, cobalt, manganese, cadmium, lead, tin, aluminum, potassium, sodium, or arsenic ions in a sample.
用于检测和区分样品中金属的传感器包括含酚基的偶氮染料,酚基具有一个参与可逆金属离子结合的羟基和一个与光学透明基质烷基化的第二羟基。这种传感器可用于检测样品中的铬、钙、镁、铜、汞、镍、锌、钴、锰、镉、铅、锡、铝、钾、钠或砷离子。
