| Abstract: | The colour reaction of T(4-MOP)PS4 with Pb(Ⅱ) is studied.The results show that heat not needed,the apparent molar absorption coefficient is 2.11×105 L·mol-1·cm-1 and linear range is 0~1.1 μg/mL,and the ability of anti-jamming is high.The proposed method is applied to determine Pb(Ⅱ) in samples such as preserved eggs,hair,tea,wine,drainage water,industrial waste drainage,food packaging bags,canned food and leek.The results are satisfying. |
