Highly Sensitive Eu3+ Doped In Sol-Gel Matrix Optical Sensor For The Assessment Of Ciprofloxacin In Different Real Samples

THE EFFICIENCY of the excited-state interaction between Eu3+ doped in sol- gel matrix and the industrial product ciprofloxacin of (CFX) has been studied in different solvents and pHs. A high luminescence intensity peak at 617 nm of europium- ciprofloxacin complex at lambda(ex)=365 nm in acetonitrile was obtained. The photophysical properties of the red emissive Eu3+ complex doped in sol-gel matrix have been elucidated, the europium was used as optical sensor for the assessment of ciprofloxacin in the pharmaceutical tablets and serum samples at pH 8.0 and lambda(ex)=365 nm with a concentration range of 5.0 x10(-9) - 1.0 x10(-6) mol L-1 for ciprofloxacin, correlation coefficient of 0.987 and detection limit of 1.65 x10(-9) mol L-1.
