共振散射光谱法测定环境水样中痕量锡(Ⅱ)
Resonance Scattering Spectrometric Determination of Trace Amounts of Tin(Ⅱ) in Environmental Water Samples
摘 要
在pH 4.3的缓冲介质中,痕量锡(Ⅱ)对氯酚红-人血白蛋白-十二烷基硫酸钠体系的共振散射光谱有明显的减弱作用,共振散射强度的减弱程度(ΔI)与锡(Ⅱ)的质量浓度之间在0.2~4.0 μg·L-1范围内呈线性关系,检出限(3S/N)为0.12 μg·L-1,用于3件环境水样中痕量锡(Ⅱ)的测定,测定结果的相对标准偏差(n=6)小于3.5%,加标回收率为95.5%~100.6%.

Abstract
In a buffer medium of pH 4.3,intensity of resonance scattering of the reaction system of chlorophenol red (CPR),human serum albumin (HSA) and sodium dodecyl sulfate (SDS) was significantly decreased by the presence of stannous tin.Linear relationship was kept between the magnitude of decrease in intensity of resonance scattering (ΔI) and concentration of Tin(Ⅱ) in the range of 0.2-4.0 μg·L-1,with the detection limit (3S/N) of 0.12 μg·L-1.In its application to the analysis of 3 water samples,values of RSD′s (n=6) obtained were less than 3.5%.Results of recovery test found by standard addition method were in the range of 95.5%-100.6%.
