Complex formation of Sudan I with Cu(II) and its identification from chilli species

摘要：

The new chemical method for identifying and quantifying Sudan I (1-(2,4-dimethylphenyl)azo-2-naphthalenol)from chilli species is devised to overcome the shortcoming with complex operation, longer analytical period of High performance liquid chromatography (HPLC) assay. Sudan I complexed with Cu 2+leads to the shift of visible absorption wavelength from 478 nm to 526 nm. The major product is the Sudan I complex with general formula Cu(Sudan I)Cl. Bonds formed between Cu 2+and nitrogen, oxygen lead to a larger conjugated system, which accounts for the bathochromic shift. The effect of several factors is investigated. The optimum amount temperature is kept at 50 ℃. For the calibration of Cu(Sudan 94% to 105%.
