Özet
A novel chemosensor APA-Rh based on rhodamine ring was developed for detection of Cu2+ and Fe3+ ions. For this purpose, the optical properties of the chemosensor APA-Rh were investigated in DMSO:H2O (4:1, v/v) in the presence of different metal ions such as Li+, Na+, K+, Ag+, Mg2+, Ca2+, Ba2+, Cd2+, Zn2+, Cu2+, Hg2+, Cr2+, Pb2+, Fe2+, Mn2+, Co2+, Fe3+, Cr3+, and Al3+. The chemosensor APA-Rh exhibited high selectivity and sensitivity for Cu2+ and Fe3+ ions among other metal ions. Detection limit (LOD), interaction stoichiometry and association constant values were calculated for Cu2+ and Fe3+ ions. LOD values for Cu2+ and Fe3+ were 1.04 ?M and 0.91 ?M, respectively. It was also found that the response time of APA-Rh was as low as 0.5 min and the other metal ions did not cause interference for detection of Cu2+ and Fe3+ ions. The results showed that the new chemosensor APA-Rh is a both colorimetric and fluorometric reversible dual sensor for Cu2+ and Fe3+ ions..
