Optically Selective Nanosensors for Trace-Level Toxic Ions

Optically Selective Nanosensors for Trace-Level Toxic Ions 

Pb analyte ions at pH 9, 3, 9.5 and 7, respectively. Note the concentration of diverse ions was in ppm, and given with the notations of interfered ions (x-axis). The inferred species were also first mixed with the monolithic sensors before addition of the analytes under working sensing conditions of 4 mg sensor, 20 ml volume and 25 °C. 

5 and 7, respectiveiy. Note the concentration of diverse ions was in ppm, and given with the notations of interfered ions (x-axis). In addition, the inferred species were 

20 ml volume and 25 °C. The abbreviation of anions were as follows CO = carbonate HCOT = bicarbonate SOj = sulfate  

SCN = thiocyanate Thiour = thiourea l03=iodate S203 = thiosulfate
