The results indicate that there is the significant linear correlation between the decoloration value and half-time and molecular descriptors, especially MW/S and number of azonic groups of azo dyes. Moreover, a QSPR model of azo dyes was achieved and used for calculation of predicted decoloration value and half-time of the dyes.

结果表明，染料分子结构描述符MW/S值、芳香环数目偶氮基数目和与I/O值与脱色率和半衰期之间存在着较好的线性相关性，其中MW/S值和偶氮基数目对脱色率和半衰期的贡献最为显著；所获得的QSPR定量关系模型可用于计算和估计水溶性阴离子偶氮染料的理论脱色率和半衰期。
