混合表面活性剂对Fe3+-CAS显色反应选择性的影响
The Effect of Mixed Surfactants on Improving the Selectivity of Fe (Ⅲ) CAS Color Reaction
【摘要】 本文研究了混合表面活性剂对显色反应选择性的影响.结果表明,CTMAB-TritonX-100对Fe3+-CAS显色反应有协同增敏作用,同时还能提高其选择性.本文还讨论了应用混合表面活性剂改进显色反应选择性的有关问题.
【Abstract】 In this paper, the effect of mixed surfactants on improving the selectivity of Fe3+ -CAS color reaction was investigated. It was indicated that the synergic sensitizing effect of CTMAB-TritonX-100 mixture on Fe(Ⅲ)-CAS system was caused and the selectivity of the color reaction was improved. Some problems about mixed surfactants improving the selectivity of color reactions were discussed.
