摘　　要：探讨染料用量、醇、pH调节剂和表面活性剂等对荧光黄染料荧光性能的影响。测试了不同实验条件下,荧光黄染料的荧光强度。结果表明,荧光黄染料的荧光强度随染料浓度的增加而增加,但当染料质量分数超过0.6%后,有下降的趋势;加入3%的醇类有机溶剂后,染料荧光强度降低幅度超过10%;染料的荧光强度随pH的增加而减少,并在pH为7~9时,基本保持不变;加入适量表面活性剂后,染料荧光强度有增强的趋势。The effects of factors such as the amount of dyes,alcohols,the pH adjusting agent,and surfactants on fluorescence properties of the fluorescent yellow dye were investigated.The fluorescence intensity of the fluorescent yellow dye was tested under different experimental conditions.And the test results showed that the fluorescence intensity increased firstly with an increasing dye concentration,and then decreased when the mass fraction of dye exceeded 0.6%.When the mass fraction of dye was 0.6%,the fluorescence intensity reached a highest value.The fluorescence intensity was reduced about 10% when a 3% alcohol solvent was added to the dye.The fluorescence intensity reduced with an increasing pH value,and remained unchanged when the pH value was 7～9.The dye fluorescence intensity tended to increase after addition of an appropriate amount of surfactant.
