the concentration of La3+ was studied using increasing volumes of a 5.1×10-4 M solution in the range of 0.05 – 2.0 mL of the reagent. The tested diluting solvents included water‚ dimethyl sulfoxide‚ acetonitrile‚ dioxan‚ ethanol‚ methanol‚ and 2-propanol. After mixing the studied drug solution with all reagents‚ the reaction mixture was allowed to stand at room temperature for different time interval and the fluorescence intensity was measured. Different surfactants were added to the reaction cocktail
