| Abstract: | The fluorescence behavior of the system and the conditions of the title method has been studied. Non-ionic surfactant op was added to increase the sensitive and stability of the determination. This method has been applied to the determinations of phosphorous in some black foods. Both the accuracy and precision are satisfactory. |
