以硅胶G胶片和滤纸作基质氟哌酸的固体基质室温燐光法研究

Room Temperaters Phosphorescence of Norfloxacine With Modified silica Gel G Chromatoplate and Filter Paper as Solid substrate

探讨了氟哌酸的固体基质室温燐光法（ＳＳ－ＲＴＰ）中的基质效应和重原于效应，经聚丙烯酸（ＰＡＡ）处理的硅胶Ｇ胶片做基质测定痕量氟哌酸较滤纸为基质具有检测限低、无需重原子微扰剂，稳定性好等优点。

The effect of the substrate and heavy atom for norfloxacine(NFLX) in solid substrate-room temperature phosphorescence (SS-RTP) has been discussed. RTP cmission of NELX was dramatically enhanced on modified silica gel G ohromatoplate with polyacrylic acid (PAA). Silica gel G chromatoplate is superior to the usual filter paper substrate in terms of background interference and antihumidity.
