摘　　要：研究了甲酸钠对活性红3BS发色体系的影响,测试了平平加O浊点温度随甲酸钠用量增加的变化情况,探索了甲酸钠/活性红3BS/平平加O体系中,平平加O临界胶束浓度的计算方法。结果显示,甲酸钠对活性红3BS的最大吸收波长没有影响,相同质量浓度的甲酸钠比硫酸钠更易使染料聚集。相同浓度的甲酸钠对平平加O浊点温度的影响小于硫酸钠。在活性红3BS/平平加O溶液中,加入相同浓度的甲酸钠比氯化钠更易降低平平加O的临界胶束浓度。The effect of sodium formate on chromophoric system of Reactive Red 3BS was discussed.When sodium formate dosage increased, changes of peregal O cloudy point were tested. And computing method of peregal O cmc was explored in sodium formate/Reactive Red 3BS/peregal O system. The results showed that sodium formate had no effect on maximum absorption wavelength of Reactive Red 3BS. When electrolyte mass concentration kept constant, comparing with sodium sulfate, sodium formate was more likely to make dyes aggregation. When electrolyte molar concentration kept constant, the effect of sodium formate on peregal O cloudy point was lower than that of sodium sulfate. Comparing with sodium chloride, sodium formate was more likely to reduce the cmc of peregal O in the solution of Reactive Red 3BS/peregal O.
