摘要
A colorimetric method for determining cyanuric chloride (CC) and for monitoring its polysaccharide gel activation, before and after ligand binding, was developed. The method is based on the reaction of CC or its activated gel with pyridine and barbituric acid or dimethylbarbituric acid. The product formed yields a purple red color with lambda max at 595 nm, and an E-M value of approximately 300,000 after 1 h at room temperature. Due to its high sensitivity, this method can detect traces of CC (1 mu M) under the above conditions. The method is fast, reliable and devoid of any side reactions.
