Abstract

The effects of different surfactants on solid substrate-room temperature phosphorescence (SS-RTP) properties of Sn(4+)-morin systems were investigated. It was found that the SS-RTP intensity of luminescence system was increased greatly in presence of sodium dodecyl sulfate (SDS). A new highly sensitive method for the determination of trace tin has been proposed based on sensitization of SDS on SS-RTP intensity of morin-tin system on the filter paper substrate. The linear dynamic range of this method is 8.0-112 ag per spot (with the volume of 0.4 microl per spot) with a detection limit of 4.0 ag per spot, and the regression equation is DeltaIp=199.7+3.456m(Sn(IV)) (ag per spot), with the correlation coefficient r=0.9998 (n=7). This simple, rapid and reproducible method has been applied to determine the amount of tin in real samples with satisfactory results.
