The colour reaction of p-ClTPPS4 with Pb(Ⅱ) was studied in this study. The results showed that complexation reaction can complete without heating, the apparent molar absorption coefficient is 2.51×105 L/mol·cm, linear range is 0~ 6μg/10ml, and the ability of anti-jamming is high. The proposed method has been applied for determination of Pb(Ⅱ) in food with satisfiedr esults.
