| Abstract: | Objective To establish a method for determing zinc released from food contact rubber products.Method Zinc soaked in 4% HAc solution was determined by flame atomic absorption spectrometry.Results The linear relationship performed well in the range of 0.1～2.0mg/L,and with 0.9998 of correlation coefficient,0.0084mg/L of the limit of detection respectively.The relative standard deviation value of the method was less than 2%（n=6） and the recovery ranged from 95.0% to 103.8%.Conclusion This method was simple,rapid and highly sensitive,it is suitable for zinc determination in food contact rubber products. |
