HCSDAA与OPE-8显色反应研究

STUDIES ON THE COLOUR REACTION OF HCSDAA WITH NONIONIC SURFACTANT OPE-8

合成了显色剂 HCSDAA ,研究了 HCSDAA与非离子型表面活性剂 OPE-8的显色反应 .在 0 .16 mol· L-1Na OH碱性介质中 ,HCSDAA与 OPE-8形成稳定的缔合物 ,最大吸收波长位于 5 80 nm处 ,OPE-8含量在 4～ 16 mg/2 5 ml范围内符合比耳定律 ,建立了光度法测定微量

The Synthesis of reagent HCSDAA and the c olour reaction with nonionic surfactant OPE-8 have been studied.In 0.16 mol·L -1 NaOH,HCSDAA reacts with OPE-8 to form a stable ion pair complex whic h has on absorption maximum at 580nm.Beer's law was obeyed for 4～16mg/25ml of O PE-8.A method for the spectrophotometric determination of OPE-8 has been devel oped.
