【摘要】 本文探讨了几种不同类型表面活性剂对铝─铁试剂荧光反应的增敏作用,发现在pH5.5的缓冲溶液中,CTMAB或Zeph均可使体系的荧光强度增强五倍。因此,在上述表面活性剂存在下可望建立测定铝离子浓度范围为0.05─0.6ppm的新荧光光度法。更多还原

【Abstract】 The sensitization of various surfactants on fluo rimetric reaction of Al with H2QSI was investigated. CTMAB and Zeph can enhance the fluoreSence intensity by fivefold at PH 5 . 5. It is possible to develop a new method for the determination of ionic aluminm concentrations ranging 0.05-0.6ppm in the presence of CTMAB or Zeph.更多还原
