A new schiff's base bis-sulfosalophen has been synthesized by Sodium salicylaldimine-5-sulphonate with 3,3',4,4'-Biphenyltetramine. Zonic ion can coordinate with the compound and enhance its fluorescence intensity. Thereby, a new spectrofluorimetric method for the determination of trace zonic has been developed. When the concentration of zonic is in the range of 1∼7μg/mL, it has a good linear relationship with F, where the regression equation and the correlation coefficient are F=205.7+282.6c Zn(μg/mL) and r=0.9935 respectively. The detectio...
